All systems are go! PBS just launched the second episode of its "Once Upon a Time in Space" miniseries on Tuesday, titled "The Russian Thing," and we’ve got an exclusive clip from the harrowing chapter that focuses on near disasters aboard the Space Station Mir in 1997.

In addition to the video, we’re also proud to share an exclusive interview with NASA's celebrated British-American astronaut Michael Foale, who is featured prominently in the new segment regarding the infamous cargo pod collision on Mir, which caused a decompression incident that became a life-threatening crisis.

Hailing from British filmmaker James Bluemel and his crew that delivered the award-winning "Once Upon a Time in Northern Ireland," "Once Upon a Time in Space" is a 4-part exploration of human spaceflight. Its weekly episodes trace pivotal events in spacefaring history via the personal experiences of astronauts, cosmonauts, and loved ones left on Earth from the birth of the Space Shuttle program to the blossoming of today’s commercial spaceflight industry.

"James Bluemel is a very perceptive director, and he was different from others that have interviewed me," Foale tells Space.

"What I loved about his method was he would dig up clips from our training or at different points when I was a brand new astronaut, looking really young and had a surfer boy haircut. I love windsurfing. He would dig up clips I don't know where from. And then he'd show it to you, and then he'd say, 'What do you think?'"

Foale — a distinguished veteran of six space missions who retired in 2013 — takes us back to that day of May 25, 1997, when a manual docking maneuver caused an unmanned Progress cargo ship to collide with Mir, ripping a large hole in the Russian space station’s Spektr module.

The crew’s valiant attempt to halt the pressure leak and save the station is like something straight out of a Hollywood thriller. With only 23 minutes of oxygen left, Foale and cosmonauts Vasily Tsibliev and Alexander ‘Sasha’ Lazutkin were able to repair the damage and stop the tumbling spacecraft from spinning wildly out of control.

"The root cause of the accident was trying to save money," he explains. "And the root cause was an attempt to do a manual docking from a large distance longer than any cosmonaut or astronaut does a manual docking from and doing it without the radar. The radar was built in Ukraine and cost $2 million in that timeframe. And the Russian managers did not want to pay Ukraine $2 million.

"So someone in the Energia corporation — they're the guilty company — decided they would try and get this crew at the last minute to try and do a manual rendezvous and docking without the radar from about a six-kilometer starting point. And that test was with a Progress we'd already filled up with trash and was meant to be de-orbited into the Pacific Ocean. Before it was going to be de-orbited finally, it was going to do this test."

Unfortunately, that test went horribly wrong due to Vasily Tsibliev not being able, based on measurements he could make in real time, to determine the exact closing velocity of the Progress.

"He couldn't ascertain distance very well, but you need the distance first, and then you need to divide by time to get the velocity,” notes Foale. “That was not possible in that situation and never attempted again. It caused a much higher velocity than Vasily could extinguish using the one thruster set that were turned on the Progress.

"So it bounced off, literally bounced off after crumpling part of the Spektr module and bending one of the solar arrays. The joint cracked at the base of the solar array into the module, and that's where the unseen hole is or was. And that's where the air was leaving from. It was a multiple hit that caused it to float away. And we were told as a crew about three days later, because we asked what had happened to it. They said, 'Well, engine was capable of being fired. It was capable of reorienting itself, and it de-orbited into the Pacific.'"

In the aftermath of the collision, an adapter was sent up to try and connect power back from the Spektr module into the Mir system.

"Vasily and Sasha were planned to do an internal spacewalk into the Spektr module to get to those cables that Sasha and I had had to disconnect to save the station," Foale adds. "They were going to go back in during an internal EVA. Vasily, because of the stress of the event, didn't pass the medical test done before the spacewalk, and they wire you up for a heart monitor.

"So then a day later, a call came up from the head of the program, Valery Ryumin, saying, 'Oh, Michael, you're on the radio. I'm going to ask you, would you be willing to go in and do the spacewalk inside the Spektr module instead of Vasily?'", remembers Foale. "I just knew that that was going to create a huge issue with me and Vasily because it was so humiliating for him. And he took all the blame of the collision on his shoulders, which was unfair."

Foale retired from NASA and space travel after a brilliant 30-year career with the agency and six space shuttle missions, but the lifestyle adjustment was a bit troubling at first.

“That was a depressing moment when I was being told, 'Oh, you're done,'" he shares. "I knew I couldn't survive the envy of my astronaut colleagues who are younger than me and haven't flown but once or twice. So I knew I was kind of done in space, at least with NASA. I was dreaming of being an astronaut guide like Peggy Whitson or Michael Lopez-Alegria on an Axiom mission. Those were my daydreams initially. I miss space, but I’ve found other things to replace that fun.

“I've always been turned on emotionally and romantically by soaring and flying. So living in Texas amongst the mountains with fantastic stars every night and soaring here, it's not space. It's not in a spacesuit outside the Mir looking at it, but it's pretty cool. I do go back to a much more comfortable situation in the evening, and I do ride my bike.

"As a 69-year-old now, I have a pretty good late-life pastime. But you have to make do. And hey, you have to keep telling yourself you're one of the luckiest guys around. I would say I was naively optimistic about the international collaboration in space. The show that James Bluemel has put together, "Once Upon a Time in Space," in some ways it looks like a fairytale to me when I look back on it."

"Once Upon a Time in Space's" "The Russian Thing" episode aired on July 21, 2026, at 9:00 p.m. ET on PBS, PBS.org, and the PBS app, with the final two chapters coming on July 28 and Aug. 4.

On Episode 220 of This Week In Space, Rod Pyle and Tariq Malik are joined by Dr. Pascal Lee and astrobiologist Dr. Penny Boston to mark the 50th anniversary of Viking 1's landing on Mars.

This week, we cover how Starship Flight 13 finally prepares to launch amid a legal battle over SpaceX's proposed land swap at Starbase, plus a Chinese Long March 3B rocket gets struck by lightning during liftoff, yet still delivers its satellite safely.

Then, we revisit the Viking 1 mission's groundbreaking life-detection experiments and the decades-long controversy over what they actually found. The conversation traces Mars exploration from the earliest Mariner flybys through Viking's ambiguous, still-debated results — later explained by perchlorates in the Martian soil — and the fierce scientific rivalry the findings sparked.

Fixing a problem inside one of the world's most sophisticated scientific observatories might seem like the kind of challenge that demands a multimillion-dollar upgrade or revolutionary new technology.

But for scientists working on the Laser Interferometer Gravitational-Wave Observatory (LIGO), which listens for ripples in spacetime generated by cosmic collisions like merging black holes, the solution to a mild but persistent engineering challenge turns out to be as simple as an off-the-shelf camera.

By pairing commercially available thermal imaging cameras with computer models, a team led by Jonathan Richardson at the University of California, Riverside, has developed a technique that corrects tiny, heat-induced distortions in the observatory's mirrors — an elusive flaw that scientists say currently limits how far into deep space the facility can look.

"It doesn't require any new technology development, which is almost unheard of for solving a LIGO instrumentation problem," Richardson said in a statement.

Once incorporated into LIGO's upcoming upgrade, Richardson and his team estimate the fix would extend the observatory's reach by roughly 33 million light-years.

That gain might sound like a drop in the ocean against the unimaginably vast scale of the universe, but because space expands in three dimensions, pushing a detector's reach even slightly opens up an exponentially larger window of space. Being able to look further into the universe will allow astronomers to "hear" many more cosmic ripples, in turn increasing the potential for discovering the universe’s most violent collisions that lie beyond LIGO's reach today.

LIGO detects these cosmic ripples, known as gravitational waves, using twin L-shaped facilities in the U.S. — in the states of Washington and Louisiana. Inside each detector, a laser beam shoots down two 2.5-mile-long (4-kilometer-long) tunnels, bouncing off pristine mirrors at each end. When a gravitational wave passes through Earth, it subtly stretches one tunnel and squeezes the other. That microscopic shift alters the laser beams ever so slightly, producing a tiny flicker of light that alerts scientists to a distant cosmic event.

Because these cosmic signals are inconceivably small, preserving every single photon is crucial. To accomplish this, LIGO relies on mirrors polished to reflect 99.9999%t of the laser light that strikes them, ranking them among the purest optical components ever built.

Yet even these near-perfect mirrors have had one unavoidable flaw. The mirrors still absorb a tiny fraction of that intense laser light. That energy turns into heat, warping the mirror's surface by just a few nanometers, enough to distort the laser beam and reduce the observatory's overall sensitivity.

Physicists already knew they could counteract these distortions by applying targeted heat to the back of the mirrors. The difficult part was measuring the distortions accurately enough such that the correcting heat could be applied with exact precision.

The new technique uses infrared thermal images and existing computer models to reconstruct a map of distortions across the mirror's surface.

"You can think of it like taking an infrared picture of a car engine," Richardson said in the statement. "An engineer can look at the temperature pattern on the outside and infer what's happening inside the engine. We're doing the same thing with LIGO's mirrors."

And the technique isn't just a fix for LIGO. It is also expected to become part of the foundational design for Cosmic Explorer, a proposed next-generation U.S. gravitational-wave observatory targeted for the mid-2030s.

With 25-mile-long (40-km-long) arms — 10 times larger than LIGO's — Cosmic Explorer is already designed to detect gravitational wave events far beyond the reach of today's observatories. This new technique will only supercharge its ultimate reach.

"The goal for the next generation of gravitational-wave detectors is to achieve about 10 times the sensitivity of today's instruments," Richardson said in the statement. "One of the key obstacles to achieving that is reducing the fundamental quantum mechanical noise that limits the precision of the measurements."

The technique is described in a paper published July 16 in Classical and Quantum Gravity.

A U.S.-Russian crew will return to Earth from the International Space Station early Sunday morning (July 26), and you can watch their homecoming live.

A Soyuz spacecraft carrying NASA astronaut Chris Williams and Sergey Kud-Sverchkov and Sergei Mikaev of the Russian space agency Roscosmos is scheduled to undock from the orbiting lab on Sunday at 3:02 a.m. EDT (0702 GMT).

The Soyuz, known as MS-28, will land on the steppe of Kazakhstan about 3.5 hours later, at 6:26 a.m. EDT (1026 GMT). You can watch these milestones here at Space.com, courtesy of NASA.

The coverage starts today (July 25) at 9:40 a.m. EDT (1340 GMT) ahead of a change-of-command ceremony aboard the International Space Station (ISS). Kud‑Sverchkov will hand over the reins of the orbiting lab to NASA astronaut Jessica Meir, part of the transition from ISS Expedition 74 to Expedition 75 (which officially begins when Soyuz MS‑28 undocks). You can watch that live via NASA.

NASA will resume its webcast tonight at 11:10 p.m. EDT (0310 GMT on July 26) to cover crew farewells and the closing of the hatches between the ISS and Soyuz MS-28, which is expected at 11:30 p.m. EDT (0330 GMT).

Undocking coverage begins Sunday at 2:30 a.m. EDT (0630 GMT). The stream will pick up again at 5:15 a.m. EDT (0915 GMT) for deorbit and landing activities. Touchdown will occur southeast of the Kazakh city of Dzhezkazgan, according to NASA.

Soyuz MS-28 launched to the ISS on Nov. 27, which was Thanksgiving Day. That liftoff kicked off the first space mission for Williams and Mikaev and the second for Kud‑Sverchkov.

When it's all said and done, the trio will have spent 241 days in space on their current flight. They will have orbited Earth 3,856 times and traveled a total of more than 102 million miles (164 million kilometers).

After touchdown, the three spaceflyers "will fly by helicopter to Karaganda, Kazakhstan, where recovery teams are based," NASA officials wrote in a media advisory. "Williams then will return to NASA's Johnson Space Center in Houston, while Kud‑Sverchkov and Mikaev head back to their training base in Star City, Russia."

SpaceX launched the world's most powerful rocket on a critical 13th test flight late Friday, but there was no triskaidekaphobia on this mission.

The July 24 test launch, Space's Starship Flight 13 mission, sent a towering rocket the size of a 40-story skyscraper into space from South Texas, returned its massive Booster to Earth, and then — in a feat perhaps none saw coming — gently landed its Starship upper stage in the Indian Ocean, where it tipped over to float belly up on the sea.

"Starship is intact, floating in the ocean and transmitting telemetry!" SpaceX CEO Elon Musk wrote on X.

"That is a first," SpaceX spokesperson Dan Huot added in live commentary as a drone beamed stunning views of Starship bobbing in the waves. "That is the softest splashdown we have ever had with Starship in the Indian Ocean."

The splashdown capped what appeared to be a mostly successful test flight of SpaceX's biggest Starship ever. With a mighty roar, Starship Flight 13 lifted off from SpaceX's Starbase, Texas launch site at 6:51 p.m. EDT (2251 GMT) on a test flight that lasted just over one hour.

It was only the second flight of the company's new Starship Version 3 design, or V3, and SpaceX was hoping for a better outing than its first attempt in May. During that previous test, the Starship Flight 12 mission, the massive Super Heavy first-stage Booster suffered engine problems after stage separation and failed to make a water landing in the Gulf of Mexico. It crashed instead.

Lucky Flight 13

Friday's Starship Flight 13 mission fared a bit better.

SpaceX initially tried to launch Flight 13 on July 16, but the rocket aborted the try at the last second due to engine issues. SpaceX replaced some first-stage Raptor engines in time for a July 23 launch attempt, but waved off due to weather, setting the stage for Friday's successful liftoff.

Minutes into the flight, the Super Heavy Booster successfully separated from its Ship upper stage, aced a flip maneuver and returned to Earth. There was a problem during the landing burn. Only five engines appeared to fire when 13 were required to slow the Booster to landing speed. It hit the Gulf waters harder than planned, its camera views cutting out.

"It didn't look like we lit all 13 engines that we were planning for that initial landing burn," Huot said. "We were targeting a softer splashdown and, as you saw, it came in with quite a bit of velocity."

Starlink V3 makes a debut

Despite the Booster's rough landing, there were clear successes on Starship Flight 13.

While sailing on its suborbital trajectory, Flight 13's Ship upper stage deployed 20 next-generation Starlink Version 3 internet satellites — large, flat satellites equipped with laser communications links and expansive solar arrays that will replace SpaceX's current Starlink internet megaconstellation.

Starship is designed to launch 60 Starlink V3 satellites at a time, spitting them out through a slit-like payload bay door like a giant PEZ candy dispenser. All 20 Starlink V3 satellites deployed smoothly, with the last two switching on flashlights and looking back at their Ship carrier before floating off into orbital darkness. The satellites did not stay in space. They fell to Earth and burned up (by design) due to their suborbital flight path.

The Ship upper stage (which SpaceX also refers to as Starship) then reignited one of its six Raptor engines to test a critical engine relight capability that will allow future Starships to enter and leave orbit. The burn went off without a hitch — a milestone since SpaceX had not always performed the burn if a test didn't go smoothly.

Then it was time for reentry, with cameras beaming back stunning views of Starship wrapped in super-hot plasma as it fell back to Earth. The spacecraft executed a three-engine burn to flip over into a vertical landing position, but did shift down to two engines, then one before it toppled over to rest on the waves.

The sight of a floating Starship triggered a cacophony of cheers from SpaceX teams at Starbase and its Hawthorne, California rocket factory in the company's livestream. After all, Starships usually explode after they tip over.

"This is just the first time we've put a Starship into the water," SpaceX's Dan Huot said during live commentary. He called it SpaceX's "softest splashdown" ever. "This is a dream scenario for this team that's trying to get this heat shield data."

The heat shield isn't the only thing SpaceX's recovery team will be looking at.

Live views from Starship showed its six engines intact along with its flaps and other systems. Teams will be poring over what they can retrieve from the sea to help improve future Starship upgrades.

SpaceX is developing Starship to be a fully reusable launch system, a 407-foot-tall (124 meters) megarocket capable of taking Starlink fleets to orbit as easily as it lands NASA astronauts on the moon. That part is key.

NASA has tapped SpaceX's Starship to land its Artemis IV astronauts on the moon in 2028, but SpaceX has yet to ever complete an entire Earth orbit with Starship after 13 test flights and three years of launches. It's been a decade since Elon Musk first unveiled what SpaceX now calls Starship during a 2016 speech.

Over the next two years, SpaceX must not only send a Starship into orbit. The company also aims to return a Ship to Earth to catch it in the "chopsticks" of its Mechazilla launch pad at Starbase. (The company has already done so with its Super Heavy Booster stages.)

SpaceX also must successfully demonstrate in-space Starship refueling, complete an orbital tanker version of Starship, and finish a crewed lander version complete with a life support system that can keep astronauts alive on the moon. That's a lot on the Starship to-do list and NASA is watching.

"Congrats on getting Flight 13 underway," NASA Administrator Jared Isaacman wrote on X after the launch. "Excited for what will be learned from this mission. When Starship comes online, its capabilities will be game-changing, not least of which will be ensuring we never give up the Moon again!" In a lunar coincidence, Friday's launch coincided with the 57th anniversary of the Apollo 11 astronauts' return to Earth after their historic moon landing flight.

But for now, SpaceX is clearly celebrating.

"I'm a little over the moon right now," Huot said. "Wow. Lucky number 13. Hell of a great day for Starship."

Smart telescopes like the Seestar S30 Pro have changed astrophotography and, arguably, urban astronomy. The Seestar S30 Pro takes that concept further than most. Small enough to fit inside a camera backpack, it combines a refractor telescope, motorized mount, dual cameras and image-processing software into a compact unit controlled entirely from a smartphone. Within minutes of powering on, it can align itself to the night sky, slew to a specified target and begin stacking exposures to reveal galaxies, nebulas and star clusters — even from light-polluted locations.

It makes astrophotography — once a complex and expensive hobby — possible with a single, automated device, though what makes the Seestar S30 Pro particularly interesting is not just its simplicity, but how it changes the experience of observing. Instead of actively operating a telescope, users watch a digital image build in real time. Sure, your eyes don’t see the photons coming from distant galaxies, but that misses the point — urban astronomers can’t see much of those galaxies anyway when using an optical telescope.

Positioned as an upgrade to the original Seestar S30, it introduces higher-resolution 8.3MP imaging, equatorial tracking support and expanded imaging modes aimed at more advanced users.

Designed for beginners, urban astronomers and astrophotographers of any level who are looking for a portable rig, the Seestar S30 Pro is about convenience, capability and a different way to explore the night sky.

ZWO Seestar S30 Pro smart telescope review

ZWO Seestar S30 Pro: Design

• Lightweight design
• Dual-camera system
• Full smartphone control

At first glance, the Seestar S30 Pro barely resembles a telescope, being closer in size to a telephoto lens than a traditional optical instrument. That portability is one of its defining strengths — this is a telescope you can realistically take anywhere, whether into a backyard, onto a balcony or on a dark-sky trip. You could even take it as hand luggage on a trip to see a total solar eclipse in a distant land.

The design is deliberately minimal. Aside from a power button and USB-C slot, there are no physical controls. Everything — from slewing and focusing to image capture and processing — is handled through the Seestar app. Once connected to a phone via its own WiFi network, the system operates entirely offline, connecting directly to your phone without requiring an internet connection in the field.

A key feature of this new, improved model is its dual-camera system. The primary telephoto camera is dedicated to deep-sky imaging, using a Sony IMX585 sensor that’s capable of 8.3MP (4K) images, while the secondary wide-angle uses an equally capable Sony IMX586 sensor for sky alignment and wide-field imaging modes.

The included tabletop tripod is solid, if small, so users with backyards surrounded by buildings or trees will benefit from mounting the device on a full-size photographic tripod. It also comes with a handy, high-quality padded shoulder bag to store the telescope and all its accessories.

ZWO Seestar S30 Pro: Performance

• Automatic stacking with intelligent frame rejection
• EQ mode enables longer exposures
• Strong results under urban/suburban skies

Using the Seestar S30 Pro is less about operating equipment and more about using an app. After powering on and connecting via WiFi, the telescope automatically plate-solves the stars overhead, determines its position and slews to a selected target. Within minutes, it begins capturing short exposures — typically around 10 seconds — which are stacked in real time to reduce noise and improve detail. Crucially, the system automatically discards poor-quality frames caused by tracking errors, wind shake or star trailing.

The effect of the image stacking is gradual. As more data is collected, a faint patch of light slowly resolves into a nebula or distant galaxy. The longer the telescope runs, the clearer and more detailed the final image becomes, with nebulosity and spiral arms becoming visible. Stars remain sharp across the field of view — the Seestar S30 Pro’s optics may be small, but they are excellent quality. During our test, we produced some superb images of the Orion Nebula (M42), as well as Bode’s Galaxy (M81) and the Cigar Galaxy (M82), the Whirlpool Galaxy (M51) and the Great Globular Cluster in Hercules (M13).

Stacking images is a hugely effective way to do observational astronomy under light-polluted urban skies. By stacking multiple exposures and applying built-in filters (there are three), the Seestar S30 Pro can reveal objects that would otherwise be invisible through the eyepiece of a traditional optical telescope.

The all-new equatorial (EQ) mode extends performance further, though aligning the telescope with Earth’s rotation requires purchasing the add-on Seestar TH10 Fluid Tripod Head. This is easy to set up, thanks to an in-app setup process that perfectly positions the tripod and ball head. With Expert Mode engaged, exposures of up to 60 seconds are possible. We tried it on two faint targets — the Whirlpool Galaxy (M51) and the Great Globular Cluster in Hercules (M13) — and got much greater detail.

Planetary imaging is less impressive, with planets appearing small and lacking fine detail. That said, we did manage to image Jupiter and its moons. The telescope is clearly optimized for deep-sky imaging rather than solar system work — the exception being the moon, which looked fabulous through the Seestar S30 Pro.

ZWO Seestar S30 Pro: Functionality

• Intuitive smartphone app
• Automated imaging and Plan mode
• Built-in processing and FITS export

The Seestar app is central to the entire experience. It acts as both controller and processing platform, offering a planetarium-style sky atlas that displays objects visible from the user’s location. Selecting a target triggers automatic alignment, slewing and image capture. Once imaging begins, the app displays real-time progress, including exposure count and total integration time. Users can stop a session at any time or continue it for deeper results. The telescope can operate largely unattended, making it easy to leave running and check later.

If all of this is beginning to sound like the Seestar S30 Pro is ideal for lazy astronomers, it doesn’t end there. Cue the app’s Plan mode, which allows users to schedule multiple targets for imaging overnight. Orion Nebula not rising until 3 a.m.? No problem. Pre-sunrise comet? Stay in bed. Assuming you’ve checked for clear skies beforehand, the Seestar S30 Pro can observe while you sleep. However, Plan mode does come with limits: exposure time and gain cannot be fine-tuned per target, so users must rely on default settings. For most, that won’t deter.

For those interested in post-processing, the Seestar S30 Pro supports FITS file export, enabling images to be refined in external software such as Siril, PixInsight, DeepSkyStacker or Photoshop (though advanced users dealing in FITS files may find that the system’s 128GB internal storage needs frequent attention). Alternatively, the built-in Deep Sky Stack provides quick results with minimal effort, allowing frames to be discarded and the effective AI Denoise pipeline to be engaged — something that takes a little patience, but delivers excellent results.

How we tested the ZWO Seestar S30 Pro

Testing took place over multiple nights during late winter and early spring, under suburban Bortle 6 skies in cold but not freezing temperatures. It was also used in Bortle 2 skies in sub-zero temperatures, with no ill effects on the 6-hour battery life. The telescope was used to image a variety of deep-sky objects, with sessions ranging from short captures to integrations lasting several hours. Both standard alt-az mode and EQ mode were tested.

Should you buy the ZWO Seestar S30 Pro?

The Seestar S30 Pro is best understood not as a traditional telescope, but as an automated imaging system designed to make astrophotography accessible. It’s also an upgrade on the Seestar S30 that may or may not be worth the money, depending on your needs.

For beginners, it provides a clear pathway into astrophotography without the usual financial or technical barriers. For more advanced users, it’s an efficient grab-and-go system for casual or supplementary imaging.

If the ZWO Seestar S30 Pro isn't for you

If you’re looking for a more affordable entry point, the ZWO Seestar S30 offers similar ease of use, but with lower (2MP) resolution and fewer advanced features. For those who simply want basic, shareable images, it remains a strong alternative.

The DwarfLab Dwarf Mini is even smaller and more portable but it is limited to 2MP imaging. At the other end of the market, the Unistellar Odyssey is a premium smart telescope offering much larger apertures and access to citizen science campaigns, albeit at significantly higher prices.

Henry Alonso Myers and Akiva Goldsman are the primary ringleaders behind "Star Trek: Strange New Worlds", and they're about to unleash the next cluster of 10 Season 4 episodes for their spirited space show.

With an abundance of genre-crossing indulgences that are scary, surreal, and sometimes silly, the Paramount+ hit is operating at full warp speed in this penultimate outing, the debut episode of which just premiered on July 23, 2026.

We hitched a ride with the acclaimed executive producers to learn all about their vision for "Strange New Worlds'" fourth season and why they believe it will prove to be the finest one yet, taking cues from ‘90s-style time-travel odysseys, haunted starships, noir crime thrillers, puppet mishaps, and utopian fantasies.

"It’s hard to come up through the ‘90s and not feel affected by a lot of the films that came out in that era, some of which my partner is directly responsible for," Myers tells Space regarding the solid one-two punch of the first two episodes.

"I think part of the goal is to come out swinging when you do a premiere. It needs its own premise that stands on its own, and then you need to figure out how to set up everything else for the season through that.

"How do you tell an emotional story that expresses where the season is going to go? And also, we want something that we think is cool. The minute we started talking about doing dinosaurs [In "Valles Marineris"], we were like, 'Yeah, let’s figure out a way to do that.' Then it became a question of how do we fit all of this into the same box."

For the unsettling (and pretty gruesome) horror episode titled "The Griffin Incident," Myers admits that Goldsman is his true north for all the horror elements because the Oscar-winning screenwriter loves it so deeply.

"I always look to see his reaction if whether or not we feel like we've hit it. And every season we’ve tried to do one, and we’ve done some decent ones. But we haven’t quite done something like a ghost story. His reaction to that made it all worth doing."

Goldsman finds it interesting that he understands the rules of the horror genre, yet he actually doesn't watch that much horror anymore, short of the horror projects that he's somehow been involved with creatively.

"The older I get, the harder it is for me to watch," he reveals. "This particular convergence of the open-hearted optimism of 'Star Trek' and the kind of haunted nature of the world behind the world. There's a cadence to this, an almost Lovecraftian sense of there’s something out there that’s more than we know and maybe not so pleasant. I just think that is really interesting in 'Star Trek.' So we built it and shot it like a horror movie, and for me it worked. It’s nice and scary.”

In choosing some of their favorite moments of Season 4, Myers and Goldsman share observations on a few key crew members as they embark on their own inner voyages.

"There is stuff that Uhura goes through this season that really gets me," notes Myers. "She was the new recruit at the beginning of the show, and this is the part where she's suddenly a bit more in charge. She also manages to risk her life and save people in ways we haven't seen on screen. And it builds to something I love, which is she looks at who she's going to be, and looks back at who she was, and has some really great emotional stories around that. I love seeing her on that journey."

Picking his pair of intrepid Starfleet officers, Goldsman looks toward Sickbay.

"I think there's a set of relationship beats between M’Benga and Chapel in the back half of the season that really deepens both those characters and helps us understand where everybody's going that I think Jess and Babs did beautifully," he adds. "So I’m really looking forward to that."

"Star Trek: Strange New Worlds" Season 4 is now streaming on Paramount+.

Scientists have measured temperatures beneath the surface of Jupiter's volcanic moon Io, offering the first-ever glimpse of the hidden heat driving the most volcanically active world in the solar system.

During close flybys of Io in late 2023 and early 2024, NASA's Juno spacecraft turned its Microwave Radiometer (MWR) instrument toward the moon, probing roughly six to 20 feet (two to six meters) beneath its surface. Originally designed to peer through Jupiter's thick clouds, the instrument instead revealed a powerful new way to study how heat moves through planetary crusts, according to a statement from the space agency.

"The surprising discovery that we could see below a rocky moon's surface has important implications for studying Earth's volcanoes," Scott Bolton, coauthor of the study and Juno's principal investigator, said in the statement. "Juno has taught us that if we look with an MWR-type instrument near a volcano on Earth, we might see a similar signature in the subsurface temperature gradient, providing new information on how terrestrial volcanoes work."

Until now, researchers had relied almost entirely on infrared observations, which detect only the temperature of Io's surface. By probing several feet underground, Juno has revealed how heat moves through the moon's crust for the first time.

The measurements showed temperatures rising by more than 40 degrees Fahrenheit (22 degrees Celsius) just a few feet below the surface — far more than sunlight alone could explain. Juno's subsurface heat map also revealed localized regions of elevated heat, with temperatures measuring between 18 and 36 degrees F (10 to 20 degrees C) warmer than the surrounding terrain, according to the statement.

Juno's observations uncovered another surprise, too. Despite being known for its towering mountains and active volcanoes, much of Io's surface appears remarkably smooth and composed of unusually low-density material. Researchers think the moon is blanketed by porous layers of volcanic ash, sulfur frost and other eruptive debris that continually resurface Io, burying older terrain beneath fresh deposits.

Scientists think the heat detected beneath Io's surface could be rising steadily from the moon's molten interior through a conductive crust or coming from pockets of cooling lava flows trapped just below the surface. Either way, the data provide the clearest picture yet of how Io transports heat from its interior.

Unlike Earth, where volcanism is driven largely by heat from radioactive decay, Io is continuously stretched and squeezed by Jupiter's immense gravity as it orbits the giant planet. This constant tidal flexing generates enormous amounts of internal heat, fueling hundreds of active volcanoes and making Io the most volcanically active object in the solar system. By improving scientists' understanding of how heat and magma move beneath a planet's surface before eruptions, the same microwave techniques used by Juno could one day help researchers better monitor Earth's volcanoes and improve eruption forecasting.

"Io provides a unique window into learning how tidal heating works throughout the cosmos, a fundamental process that provides energy and heat to worlds that are far from their parent star," Bolton said in the statement. "This process can not only create the most volcanic body in the solar system, in the case of Io, but also fuels the subsurface oceans on the moons of giant planets, such as Europa and Ganymede. Up until this point we could only observe the heat escaping at the surface or through eruptions. Now we can characterize how the heat is moving from the interior toward the surface."

Because Io is an extreme example of volcanic activity, it serves as a natural laboratory for studying how heat moves through planetary crusts. Those insights could help scientists better understand ancient volcanism on Mars, Venus, and Earth's moon, whose landscapes were shaped by massive eruptions billions of years ago.

The technique could also aid the search for life elsewhere. While Io itself is far too hostile to support life, microwave instruments can also probe beneath icy surfaces. Juno has already used the same instrument to study Jupiter's moons Europa and Ganymede, where scientists believe vast oceans lie hidden beneath thick shells of ice. Understanding how heat moves through those crusts is key to determining whether they could harbor environments suitable for life as we know it.

Their findings were published July 22 in the Journal of Geophysical Research: Planets.

A planet-hunting spacecraft named Plato just passed a series of critical tests as it prepares for the challenges of outer space.

What is it?

Gleaming in the light of a laboratory, this box of electronics is actually the European Space Agency's Plato spacecraft sitting inside a special test chamber where it underwent critical tests ahead of its planned spaceflight.

The Plato (PLAnetary Transits and Oscillations of stars) probe is designed to study terrestrial exoplanets, or rocky planets outside of our solar system that are Earth-sized or smaller.

This chamber, called the Maxwell Test Chamber (which is located at the European Space Research and Technology Centre in the Netherlands), is an enclosure made of conductive metal that blocks electromagnetic fields. On top of the conductive metal are foam spikes. Combined, they block out and/or absorb all electrical signals and sounds to mimic some aspects of the environment of the vacuum of space.

In this enclosure, the team turned on Plato's electronics to make sure that signals from some of the probe's instruments don't interfere with other systems or electronics on the craft. With all other signals blocked out, scientists had a clear look into how it might perform in space.

Why is it incredible?

This test is critical as Plato will need to be able to collect data and run its instruments without interference from electronics or signals from elsewhere on the spacecraft. But it's pretty impossible to ensure that things would work as planned amidst the "noise" on planet Earth.

To get any spacecraft ready to operate in the void of space, researchers conduct all sorts of tests to make absolutely sure that they're up to the challenge. In addition to tests like this, spacecraft can be placed in extremely hot or cold temperature chambers or even shaken around to make sure that they can handle the violent conditions of a rocket launch. It's amazing how we can recreate different aspects of outer space here on Earth to prepare for these missions.

There is a particular moment every July when the night sky makes perfect sense to me. Every time I step outside at night, I instinctively look overhead for the Summer Triangle. Not because it's the most spectacular sight in the sky. In fact, the vast asterism is almost suspiciously simple: three bright stars, large enough to cut through twilight and light pollution without much effort.

Experienced stargazers quietly depend on the Summer Triangle more than we admit. People imagine astronomy involves memorizing the entire sky at once, knowing exactly where each star is and what it's called. Everyone navigates differently, but we all rely on familiar anchor points because the night sky changes quickly with the seasons.

The Summer Triangle is one of the best anchors because it appears exactly when the northern sky can otherwise feel vague and washed out during late twilight. Once those three stars appear, I immediately know where everything else is. The Milky Way becomes easier to trace. The darker regions of the sky reveal themselves. Constellations stop looking random. Suddenly, I know where the Perseids will emerge from later in the night and where to point binoculars to find summer's dense star fields without even thinking about it.

The Summer Triangle also teaches you how to see the night sky. To the untrained eye, the night sky appears as a flat backdrop of stars — hence the "blanket of stars" saying. Every time I hear that cliche, I wince. There is no blanket! The night sky has incredible depth, and there's nowhere better to learn how to appreciate that than when gazing at the Summer Triangle.

Take Altair, the lowest star. It's relatively nearby at about 17 light-years away. It shines brightly largely because it is close to us. Vega lies slightly farther away at roughly 25 light-years, but it is intrinsically far more luminous. It once served as Earth's North Star thousands of years ago and, thanks to our planet's slow axial wobble, will become the North Star again many millennia from now. So far, so local — we're in the sun's backyard with these two stars. The light from both of them began its journey to us this century.

Then there's Deneb. Deneb is so distant — roughly 2,600 light-years away — that the fact it appears this bright at all becomes genuinely difficult to process. Its light began traveling toward Earth while the Roman Empire was still in existence. The only reason it remains prominent in our sky is that Deneb is an enormously luminous supergiant radiating tens of thousands of times more energy than the sun.

Knowing this about Deneb transforms the Summer Triangle into a three-dimensional shape. Here are three stars that appear neatly connected overhead, but in reality, one is separated by an incomprehensible distance. So next time you look at the Summer Triangle, keep Altair and Vega at the front and push Deneb way, way back. It's not a triangle anymore — it's an arrow pointing far into the distance, thousands of light-years away into the starfields of the distant Milky Way.

What's happening and when to look

This week is the perfect time to reacquaint yourself with the Summer Triangle using just your naked eyes. Around 11 p.m. local time at mid-latitudes of the Northern Hemisphere, look high in the southeast. Vega is usually the first to appear, high and brilliant with a slightly blue-white color. To its lower left sits Deneb. Farther south is Altair. By midnight, the entire Summer Triangle stands high overhead and remains one of the defining features of the northern summer sky through October.

Stretching directly through it is our view into the Orion Arm of the Milky Way — the spiral arm of the galaxy containing the solar system itself — while farther south, the glowing river of starlight continues toward the galactic core near the constellations Sagittarius and Scorpius, low on the horizon. Under dark skies, the Milky Way visibly streams behind Deneb and through Altair like a river of stars.

How and when I'm watching it

Once I start slowly sweeping binoculars through the Summer Triangle, I usually lose all sense of structure and planning. Dense star clouds spill into view everywhere. Dark lanes slice through the Milky Way. Tiny clusters appear almost accidentally. The region between Deneb and Altair may be my favorite casual binocular territory in the entire sky.

Inside the Summer Triangle itself lies the Cygnus Star Cloud, one of the richest naked-eye sections of the Milky Way visible from northern latitudes. Nearby are the Ring Nebula and the Dumbbell Nebula. The beautiful double star Albireo — one bright yellow and the other a fainter blue — sits at the beak of Cygnus, the Swan.

I'll also look for a couple of smaller constellations within and around the Summer Triangle — Delphinus, the Dolphin, hovers to the left of Altair, while tiny Sagitta, the Arrow, hangs above Altair, looking improbably compact.

That's another thing the Summer Triangle taught me — astronomy improves dramatically once you stop hunting objects individually and start exploring regions instead. It's armchair travel of the grandest kind.

Stargazer's corner: July 24-31, 2026

The moon will move beneath the Summer Triangle this week, appearing as an 81%-illuminated waxing gibbous moon as it shines close to supergiant star Antares in the constellation Scorpius, on Friday, July 24. By now, the moon is dominating the night sky, albeit low on the horizon, and on Wednesday, July 29 — the night before the full Buck Moon — the Summer Triangle will appear to point straight at it. Late July also marks the gradual strengthening of the Perseid meteor shower, with occasional early meteors now appearing after midnight. The Southern Delta Aquariids and Alpha Capricornids peak around Thursday-Friday, July 30-31, though the full moon will reduce visibility of fainter meteors considerably.

Constellation of the week: Sagitta

Sagitta, the Arrow, is one of the smallest constellations, but also one of the easiest to recognize once you've found it. It appears as a short line of five stars — all between 450-650 light-years distant — with an arrowhead, shaft and two stars as the fletchings. It's between Cygnus and Aquila.

It's not bright, but it's well-defined, and once you spot it, it becomes a reliable reference point. Learning these smaller constellations helps fill in the gaps between the more obvious patterns.

Lightning struck a Chinese rocket shortly after liftoff this week, as seen in incredible video and photographs.

A Long March-3B rocket lifted off from China's Xichang Satellite Launch Center on Thursday (July 23) carrying a communications relay satellite destined for geostationary orbit. Some 30 seconds into flight, lightning struck the rocket, leading to awestruck cries from crowds gathered nearby to watch the launch.

Despite the strike, the rocket delivered the satellite to its intended orbit as planned, according to the China Aerospace Science and Technology Corporation (CASC). The satellite will help relay communications to the nation's Tiangong Space Station and other crewed missions.

This isn't the first time lightning has struck a rocket shortly after liftoff. A lightning bolt famously struck the Saturn V rocket carrying NASA's Apollo 12 mission, the second to ever land astronauts on the moon. In fact, the rocket was struck twice.

According to a report NASA issued after the mission, some non-essential instruments and sensors experienced "permanent effects" from the strikes. Nevertheless, the mission put astronauts Charles "Pete" Conrad, Alan Bean and Richard "Dick" Gordon on the moon as planned.

More recently, lightning struck a Russian Soyuz rocket in 2019 shortly after it launched. Like in this most recent example, the vehicle was able to place its Glasnost communications satellite in orbit despite the strike.

But not all rockets struck by lightning fare so well. In 1987, a bolt struck the United Launch Alliance Atlas/Centaur-67 rocket, leading to a malfunction in one of the computers that guided the vehicle and "ultimately causing the breakup of the vehicle," NASA wrote in a report of the incident.

The incident led to NASA developing strict Lightning Launch Commit Criteria (LLCC) to lower the risk of strikes by further defining weather conditions that would delay launches. "Since Atlas/Centaur-67 and the rigorous implementation of the LLCC, no other launch vehicles have intercepted or triggered lightning on launch in the United States," NASA wrote in a technical paper outlining the criteria.

Hey, Space Fans! Every weekend here at Space.com, you may have noticed we highlight the latest episode of the podcast This Week In Space, a TWiT show co-hosted by yours truly and my friend and colleague Rod Pyle, a space historian and editor of the National Space Society magazine Ad Astra.

This Week In Space episodes usually drop each Saturday, but this week we're doing something a bit different. To mark the 50th anniversary of NASA's Viking landings (Viking 1 touched down on Mars on July 20, 1976), Rod and I will host a special live taping of the podcast to discuss all things Martian starting at 1:30 p.m. EDT (1730 GMT). It should last up to 90 minutes.

Joining us on the podcast will be:

• Dr. Penny Boston, an astrobiologist and speleologist (the study of caves) with the New Mexico Institute of Mining and Technology.

During our discussion, we'll touch on the personal and scientific impacts of NASA's Viking Mars landings and look at where Mars exploration may go in the modern age. We might even discuss the best places for the hunt for signs of life: the surface or inside Martian caves?

So if you're a Mars fan or a casual space aficionado, join us today at 1:30 p.m. EDT to get a detailed look at NASA's Viking Mars landings and their lasting impact on Martian exploration.

Using NASA's long-serving Hubble Space Telescope, astronomers have discovered that a stellar explosion in the Milky Way is blasting out cosmic bullets travelling at 20 million miles per hour.

The cosmic explosion in question is V445 Puppis, which erupted in 2000 and is the only known "helium nova" in our galaxy. Though astronomers have been studying V445 Puppis for two decades, much of the phenomena associated with it were shrouded in mystery due to a vast cloud of dusty debris that surrounded this nova.

When this debris finally cleared, a team of researchers was able to peer into V445 Puppis using Hubble, NASA's exoplanet-hunting spacecraft TESS (Transiting Exoplanet Survey Satellite), and the Earth-based Very Large Telescope (VLT), along with an array of other instruments. This allowed them to discover not only the "bullets", clumps of potentially oxygen-rich gas it is firing, but also the true nature of this system. This revealed that V445 Puppis consists of a dead star hungrily feeding on a companion star that is, by itself, a rare find. Thus, this system offers scientists a rare chance to study one of the rarest types of binary systems and one of the rarest cosmic explosions.

"The origin of these 'bullets' is a mystery. We suspect that these originated post-outburst, but 'bullets' of this kind have not been observed in any other nova," team member John Mills, a researcher at the University of Warwick in the UK, said in a statement.

What is a helium nova?

Helium novas like V445 Puppis occur when a white dwarf dead star cannibalistically strips helium-rich but hydrogen-poor matter from a star that has already lost its outer layer of hydrogen, exposing inner layers of helium; forming a rare "helium star." By contrast, "ordinary" novas are explosions triggered by the buildup of stolen stellar matter rich in hydrogen, not helium.

As the material accumulates on the surface of the white dwarf (a type of stellar remnant left behind when stars around the mass of the sun die) it creates runaway pressures and temperatures that eventually trigger a thermonuclear explosion.

When V445 Puppis went nova back in late 2000, it launched vast, twin plumes of debris that resemble butterfly wings. Stretching out for more than a trillion miles, astronomers initially spotted this bipolar outflow in infrared. The nova also spawned a thick disc of dust that completely obscured the binary star system. That cloud persisted for over two decades, preventing astronomers who were investigating the expanding debris from determining what kind of stars the blast originated from.

Once the debris cleared, this team determined that the system contained a helium star, one of only a few thousand of these stripped stellar bodies to be discovered among the billions of stars that populate the Milky Way.

"The culprits behind this galactic eruption have been an enduring mystery over the past 25 years, which is why it is very exciting to confirm that this helium nova was the result of a helium star accreting onto a white dwarf," Mills said.

The findings also revealed cosmic "bullets" that are even more remarkable, as they have never been seen around any other novas. Intriguingly, the team also found that V445 Puppis may be about to go nova again, and this could lead to an entirely different type of cosmic explosion.

Is V445 Puppis about to blow its top again?

Mills found that the white dwarf in V445 Puppis has overcome its stellar indigestion and is once again feeding on its companion helium star.

This is the process that led to the initial helium nova, and could mean that another episode of this rare type of cosmic explosion is soon to occur.

That has implications for our understanding of another type of cosmic eruption, this time a type of supernova called a Type Ia supernova. These occur when white dwarfs overfeed on companions and are completely destroyed by the resultant explosion.

Scientists have long suspected that repeated helium nova eruptions could lead to final Type Ia supernovas.

A new Type Ia supernova would be exciting because these events are so regular in terms of their light emission that they can be used as so-called "standard candles" to measure cosmic distances and gauge the age of the universe.

This means that they can also be employed in the quest to understand how fast the universe's expansion is proceeding, and the influence of the mysterious force called dark energy on this process.

"I look forward to seeing how this result may help us uncover what powers other similar hydrogen-poor astronomical explosions, such as the famous Type Ia supernovas," Mills said.

The team's research was presented this week at the Royal Astronomical Society's National Astronomy Meeting in Birmingham, UK.

NASA is shaking things up for its next mission to research the sun.

The six satellites of NASA's Sun Radio Interferometer Space Experiment (SunRISE) mission are poised to launch to Earth orbit soon, to serve as an early warning system for incoming solar storms. They were originally slated to lift off on a United Launch Alliance (ULA) Vulcan Centaur rocket but have now been assigned a SpaceX Falcon Heavy, according to a NASA mission update.

SunRISE will fly to space as part of a rideshare mission sponsored by the U.S. Space Force's (USSF's) Space Systems Command (SSC). Though it's not stated specifically in the NASA release, that may be a hint as to why the mission's rocket was changed. On its most recent launch, USSF-87, Vulcan experienced an anomaly in one of its solid rocket boosters — the second such incident to occur during the rocket's four launches to date.

Vulcan succeeded in delivering the USSF-87 payload to its designated orbit on that launch, but the recurrence of the booster issue during ascent prompted the Space Force to pause national security launches on Vulcan until it could be addressed. Which mission SunRISE will be manifested on has not yet been released, but SSC has already shifted other launches between Vulcan and SpaceX's Falcon 9, so NASA's change in rockets for SunRISE could indicate either that the mission has been remanifested on a different SSC rideshare, or that another SSC mission has been shifted from Vulcan entirely.

SunRISE is a heliophysics study under the NASA Science Mission Directorate's "missions of opportunity" umbrella and is part of the Explorers Program run by Goddard Space Flight Center in Greenbelt, Maryland. It consists of six small satellites, each about the size of a mailbox. The mini-constellation's mission is led by scientists at the University of Michigan and will be managed out of NASA's Jet Propulsion Laboratory in Southern California.

The half-dozen smallsats will be delivered to an orbit about 22,000 miles (35,000 kilometers) above Earth — just above a geostationary parking altitude — and fly in a giant 10-mile (16-km) "X" formation, each extending its roughly 10-foot (2.5-meter) antenna booms to act as a single large radio telescope to track solar radio bursts. These kinds of bursts travel faster than the energetic particles from a solar storm, and precede their arrival when shot towards Earth.

Powerful solar storms, like the one that hit Earth in January, are capable of disrupting or disabling satellites by interfering with onboard electronics, sensitive instruments and communications systems. If a storm is severe enough, it can pose a radiation threat to astronauts in orbit and even airborne passengers flying near Earth's poles, where the planet's magnetic field is weaker.

SunRISE will help researchers better understand the behavior of incoming solar radio bursts, but the mission won't serve as an alert system by itself. Instead, scientists will use data collected by the spacecraft to improve prediction models for impending space weather, which in turn could lead to mitigation plans to better thwart the effects of such solar events on orbital infrastructure.

Falcon Heavy is SpaceX's heavy-lift launch vehicle, capable of launching up to 58,860 pounds (26,700 kg) to geostationary transfer orbit. It's a triple-booster rocket that consists of three modified Falcon 9 first stages, and has launched 12 times since it debuted in 2018. Four of those have delivered national security payloads to orbit, with the most recent of those, USSF-52, launching in December 2023. Falcon Heavy's most recent flight overall occurred this past April, when it sent the Viasat-3 F3 telecom satellite to orbit.

Falcon Heavy's next mission will lift off with NASA's Nancy Roman Space Telescope, currently set for no earlier than Aug. 30. SunRISE is scheduled to launch later this year, but a more specific launch window has not yet been announced.

For several years now, astronomers who study the sun have faced a little mystery — our star seemed to hold too little silver. Whenever scientists examined the sun's outer layers, they've seen significantly less silver than they've expected to find.

Where, then, did the missing silver go?

As it turns out, this mystery may finally be solved. Newly published research suggests that the sun's missing silver may have been hiding in plain sight all along.

At first, the real mystery might seem to be why you'd seek silver in the sun at all. After all, 98.5% of the sun's mass is made from lightweight hydrogen and helium. Silver is just a tiny fraction of the remaining 1.5%, which also includes traces of other heavy elements like iron and copper.

These trace elements can illuminate the history of the cosmos. Silver is thought to form when dying stars violently explode in supernovas. When astronomers find silver in the sun and other stars, they can retrace the silver's origins and how stars have evolved over the eons.

"By studying the light of stars of different types and ages, we hope to understand where silver is formed in the universe, and how it has been distributed throughout the Milky Way over time," says Sema Caliskan, the lead author of the research and now a postdoc at the University of Liège in Belgium, in a statement.

Silver is particularly interesting because it's also found in utterly ancient meteorites called CI chondrites. These meteorites formed from the same primordial matter that created the sun, 4.6 billion years ago. As a result, when scientists break into CI chondrites that have fallen to Earth, they expect to find silver levels that match those they see in the sun.

Astronomers can measure the latter from afar by looking at sunlight's spectral lines. As light streams out from the sun's heart, it crashes into the atoms of our star's outer layers, which absorb the light at certain wavelengths. Look at a spectrum of sunlight, and you'll see dark lines where light has been absorbed. Atoms of different elements absorb different wavelengths, so each element leaves a distinct fingerprint.

Scientists can pore over these spectral fingerprints to reconstruct what elements created them and in what quantities. Therein lies the mystery: The sun seemed to contain much less silver than CI chondrites would indicate. This missing silver is a source for confusion in the sun's history.

Caliskan and her colleagues wondered if astronomers were missing something. They could not visit the sun in person, but they could still find where the silver might be hidden by simulating the sun's atoms on a computer. If they could create a high-silver model that still spawned the low-silver spectral lines, that model could be a good guess for the silver's whereabouts.

Other scientists had tried this before to limited success, but their simulations had been relatively simple. As light strikes an atom, the light has all sorts of intricate effects on the atom's innards. These effects can alter how the atom absorbs the light and, therefore, change how astronomers see that light.

Past models hadn't accounted for many of these tricky "non-equilibrium effects", because simulating them is far easier said than done. They're messy and complex and they vary a great deal from atom to atom.

In fact, no known scientists had ever tried to simulate a silver atom with non-equilibrium effects before Caliskan and her fellow investigators took on the challenge. They tried with their best guesses and the power of the Tetralith supercomputer in Linköping, Sweden.

Indeed, these non-equilibrium effects seem to explain the silver mystery. Based on their model, Caliskan and colleagues calculated that the sun holds 55% more silver than astronomers have measured.

This isn't a perfect match for the CI chondrites, but it's close enough that investigators can rule out any extraordinary cause. Instead, the missing silver may have been right there, in the sun all along, simply occluded from astronomers' view by tricks of physics. Next, Caliskan and colleagues plan to use this method to simulate other types of stars.

They published their work in the journal Astronomy & Astrophysics in July 2026.

In a rare first for me, I actually used autofocus for this entire astrophotography shoot. If I'm being honest? I prefer it when shooting astro with a mirrorless camera. Why? Because it is quicker and that means more time capturing the stars and less time setting up. I can get a star in sharp focus using autofocus in half the time that it would take me to do it manually and it's way easier to focus with the shutter or back button than play about with the focus ring, especially with cold fingers.

I only managed to get out under one clear sky to test the new R6 III but it was a wonderful session at my usual dark hill spot surrounded by a sea of stars and celestial shapes. After setting up my tripod, I was ready to start shooting, armed with the Canon 14mm f/1.4 and 45mm f/1.2 lenses.

If you are a seasoned astrophotographer, you will undoubtedly have started your craft by learning how to manually focus on stars to get them crisp and sharp in the frame. Everyone does. Whilst the manual focus (MF) versus autofocus (AF) debate continues within the community, the technology for low-light autofocusing capability has come a long way since mirrorless cameras were first introduced and the R6 III is physical proof of that.

The astrophotography

You only get the luxury of being able to do this if your camera is actually good at autofocusing in low light and for starry nightscapes. All three versions of the Canon EOS R6 feature a low-light autofocus range of -6.5 exposure value (EV), so they already have a strong baseline for shooting under dark skies. The Canon EOS R6 III features a higher resolution and advanced autofocus algorithms, so the AF system actually has more data to use and is better at using it.

I was able to capture bright objects easily and start shooting without having to spend ages using manual focus for each new shot. The autofocus was powerful enough to capture at least one star in each of my frames. I simply used autofocus on the brighter points of light in my composition, waited for the green box and then switched to manual to avoid any refocusing if I decided to recompose the shot.

Bright objects were the easiest to capture, with Jupiter, Pollux and Castor easily captured in the western sky. Light pollution washed out the contrast in this shot but it was the quickest autofocus because of the brightness of the objects.

The autofocus helped me capture a range of other constellations too. With the R6 III focusing on the bright star Arcturus, along with the rest of Boötes and Coma Berenices next to the Coma Star Cluster (Melotte 111).

The shape of Leo is recognisable and the autofocus captured the brightest star, Regulus, to bring the rest of the stars in the constellation into focus. You can even spot the Beehive Cluster (M44) in Cancer, to the right of the frame and it is fairly sharp in focus. Barring some minor star trailing from my lack of a star tracker, the stars are nicely in focus, including on minor objects like star clusters.

Using the 45mm lens, I got some close-ups of some quadrilateral shapes in the sky. Hercules' prominent trapezoidal keystone is visible and one of the corners, Zeta Herculis, was picked up by the autofocus. It is not exactly a bright star, with a magnitude of 2.88, but the R6 III picked it up easily and brought the rest of the corners into focus. Whilst barely a smudge along one of the sides of Hercules, I even managed to capture the Hercules globular cluster (M13) with the R6 III and the Canon RF 45mm wide open at f/1.2.

The polygonal head of the dragon in Draco was easily captured in the centre of the frame, with bright stars Eltanin (2.23), Rastaban (2.79) and even Iota Herculis (3.8) showing prominently. The autofocus capabilities of the EOS R6 III are maximised when used alongside a lens with a very fast aperture like f/1.4 and f/1.2. Without these types of lenses, you would be much less likely to be able to autofocus on such dim stars.

The upgrades

The big question when looking at the third iteration of a camera model is to figure out if the upgrades are actually worth it. First, you have to think about your budget and also what you are using the camera for. For astrophotography, there are a few upgrades in the EOS R6 III that can be considered to see whether they are worth it.

The most noticeable upgrade on the R6 III is the resolution, which has been upgraded from the R6 II's 24.2MP sensor to a 32.5 MP sensor. On top of improved resolution for general and astrophotography, the boosted number of pixels allows the Dual Pixel CMOS AF II to collect even more data points because there are more pixels. Dual Pixel architecture splits each pixel into two separate photodiodes and allows each photodiode to read the light from the star at two different positions and allows the lens motor to bring those points together into perfect focus.

The upgraded sensor resolution combined with upgraded tracking algorithms from the flagship Canon EOS R5 II make the R6 III better at locking onto low-light points and make autofocus for astrophotography much more reliable than in previous models.

I initially expected the higher resolution to translate into more image noise on photographs but this was not the case. The R6 III utilizes dual-gate gain architecture, which means that every pixel has a switchable path at the hardware level depending on the ISO level used and allows images with higher ISOs to have a heavily reduced base amount of noise and thus makes them less grainy.

Photos at lower ISOs on the R6 III have an incredibly high dynamic range (HDR) thanks to the low conversion gate (LCG) circuit. This allows the natural color of the stars to be preserved instead of coming across as indeterminate white blobs, as well as the subtle hues of the dark surrounding sky in the photograph.

Aside from the technical aspects of how the resolution improves the autofocus, the detail in images from the R6 III is noticeable and is great for picking up finer stellar structures such as star clusters and smaller stars. When paired with a distorted lens like the Canon RF 7-14mm f/2.8-3.5 fisheye lens, extra resolution really helps details pop. I didn't get to use the fisheye lens for astro but general daytime shooting delivered some high-quality photographs.

The final important upgrade on the R6 III is the inclusion of a CFexpress card slot, which allows faster writing and reading speeds both in camera and during media downloads. A UHS-II SD card has an average read speed of 300MB/s and an average write speed of 260MB/s.

This may seem fast but the most advanced CFexpress cards have a read and write speed of over 3000MB/s, which makes huge workloads so much easier to process. This may only be of benefit to professional photographers who shoot a lot of video or need to do a huge amount of burst photography in RAW format, but it does vastly improve the performance of this camera. Bear in mind that CFexpress cards are much more expensive than SD cards and require an additional CFexpress reader to transfer data to a computer.

Is it worth it?

The price difference between the R6 Mark II and the Mark III is just under $1000 and for that amount of money, justifying the move up to the latest model comes down to a few factors that you will have to consider. The power of the low-light autofocus is tempting but you should think about the camera as a whole to see whether it is worth making the investment.

If you are looking to boost resolution in your night-time scenes and have been shooting astrophotography for a long time, the R6 III could be worth the extra investment thanks to the 32.5MP sensor, which retains the powerful dual-gain architecture for getting high dynamic range images at lower ISOs and delivering high ISO images with significantly less grain.

If you have a heavy workflow, you are likely to be frustrated with the lack of a CFexpress card slot on the earlier R6 models and would benefit from the advanced functionality the new slot will give you, especially if you shoot a lot of RAW imagery and video.

Stick with an earlier model or a different mirrorless camera if you are a very casual astrophotographer who does most of your shooting in the daytime. I just can't justify the massive jump in price for basic shooting, where a beginner or intermediate photographer's money might be better spent on getting a fast f/1.4 lens for superior astro. I used the Canon RF 14mm f/1.4 lens for astrophotography testing and I don't think the images would have looked half as good if I had used a lens with a smaller aperture. If you already own the R6 II, the only reason you might upgrade is if you need to do more heavy cropping into your images or need better hybrid video functionality from a camera.

LOS ANGELES — Standing in the shadow of the space shuttle Endeavour, a group of retired NASA astronauts announced their plan to travel the country visiting colleges to try to inspire younger generations to get out and vote. This campaign comes as we lead up to the November midterm election.

This past year, a group of retired NASA astronauts teamed up for a single cause: to defend the U.S. constitution. They banded together as part of a non-profit, non-partisan activist organization called Astronauts for America. So far, they have been speaking out, using their astronaut expertise, platforms, cultural relevance and role model status to speak out in support of "science, evidence-based decision-making, public service and the rule of law," their website reads. Now, as the group announced at an event at the California Science Center's new air and space center — home to the shuttle Endeavour — they're hitting the road on a campaign tour of colleges called "Vote for Freedom."

"We have to do what we can to ensure that the country makes it through the challenges that we're dealing with here, and that is the message that we're going to be taking to colleges and universities," Apollo 9 astronaut Rusty Schweickart told Space.com. "And the agency that we have, the immediate agency, is to vote."

This tour will send astronauts from the group on a four-month jaunt across the country. Astronauts from the group's more than 100 members will visit state and community colleges, county fairs and even town halls, aiming to reach first-time voters and young people who might be new to voting.

"I'm really excited to look a bunch of younger Americans in the eye and make sure that they know that someone that they can trust said: ;Listen, you matter, because our country matters, and our country needs you,'" former NASA astronaut Cady Coleman told Space.com.

"It's with a uniquely American kind of freedom that we were able to go to the moon, and that same freedom launched the spaceship behind us 25 times into space. Now we see those freedoms under heavy threat," former NASA astronaut Steve Smith said during the event. "We're seeing chaos instead of community, violence instead of votes, lies instead of laws, and fear instead of fate. That's how democracy and freedom die."

"The mission is all that matters. Now, our country is the mission, and our message is simple: going to the polls is one small step for you, and one giant leap for our country," Smith added.

This campaign leads up to the U.S. midterm elections this November. Midterm elections happen halfway through every four-year presidency. This election allows voters to decide what Congress looks like, and which political party controls Congress. This can ultimately have a major impact on what laws and decisions are passed moving forward, and whether Congress will reject or change actions by the president moving forward. And this group of astronauts is serious about the importance of getting people out to exercise their right to vote.

"I'm a child of the segregated South; I grew up in Columbia, South Carolina," former astronaut and NASA Administrator Charlie Bolden, who also serves as a steering committee member for Astronauts for America, said at the event. "I graduated in 1964. Anybody know what happened in 1964? The Voting Rights Act. So, as a person growing up in my hometown, it wasn't a guarantee that my mom and dad were going to be able to go out and vote. I look at what's going on today about people trying to restrict the ability of people to cast their ballot. That's not who we are. That's not America."

The group of astronauts recently spoke out about voting access after the U.S. Supreme Court ruled in favor of protecting the right to absentee voting, in response to attempts by the Trump administration to place restrictions on the current voting process. Especially leading up to the November midterms, each vote carries significant weight. And while this nonpartisan group isn't telling you who to vote for, they do think that everyone who can should vote.

"As astronauts, we signed an oath to our nation, and we are mission-oriented people. And our nation is now the mission," Coleman added. "We need to recognize that everyone's voice is important, and one of the voices that we don't hear very much is the young people. And we want them to understand that, even though sometimes change can seem daunting, their perspective is really important, and, you know, their voice is important."

In satellite data captured over Antarctica, what appears to be a beautiful, colorful hummingbird emerges from the crest of a mountaintop.

What is it?

While there are no hummingbirds flying around Antarctica, we can see what looks like a small, purple bird in a new satellite image of an Antarctic mountain. The dark belly of this "bird" at the center of this image is actually the top of the mountain Nunatak Zaterjavshijsja in East Antarctica.

What looks like a bird's tail is a stream of ice flowing northeast all the way out to the ocean, and what appear to be feathers splaying outward from the mountaintop are actually crevasses down the mountain. These crevasses are formed by a glacier fracturing the mountain's surface as it flows in the icy current toward the ocean.

This view was captured by radar instruments onboard the satellite NISAR (NASA-ISRO Synthetic Aperture Radar) that launched as a collaboration between NASA and ISRO (Indian Space Research Organisation). The director of NASA's Earth Science Division called NISAR "the most sophisticated radar we've ever built" in a pre-launch briefing last year.

Why is it incredible?

At first glance, this image is puzzling. What could it possibly be? Its bold colors and sharp lines evoke almost alien qualities. But the strange beauty of the shapes and colors in this satellite image reveal important information about glacier movements on the mountain.

"First, it's a beautiful image, with rich details of features that provide insights to how the glacier is moving. Then, because radar can often see through snow and deep into the ice, NISAR can observe fundamentally different properties of Antarctic ice than can be seen in optical imagery," Seongsu Jeong, the signal analysis engineer who produced the image at NASA's Jet Propulsion Laboratory, said in a statement. "With NISAR we're seeing what's hidden beneath the surface."

And now anyone can explore NISAR's data. Earlier this week, on July 20, NISAR started making the data from its radar instruments public. Moving forward, mission teams will be rolling out this data so researchers everywhere can use it to study and protect our ever-changing planet.

If you're of a Martian persuasion, "Strange New Worlds"' season 4 opener couldn't have timed itself much better.

Not only does this week mark the 50th anniversary of Viking 1 touching down on the surface of the red planet, new research from University of Oxford scientists recently suggested that Mars once had an active, interconnected system of magma beneath its surface. If accurate, this discovery might have made our Solar System next-door neighbor more habitable in its distant past.

While life on Mars has long been an obsession of sci-fi creators — from HG Wells' "War of the Worlds" to "Doom" via John Carter and John Carpenter — "Star Trek"'s Martians have tended to be human expats. Indeed, by the 24th century of "The Next Generation", "Deep Space Nine" and "Voyager", it's home to the Utopia Planitia Fleet Yards that would later be destroyed by rogue synths ahead of "Star Trek: Picard"'s debut season.

SPOILERS AHEAD! ANYONE YET TO WATCH "VALLES MARINERIS" SHOULD PROCEED WITH CAUTION TO AVOID VIOLATING TEMPORAL PRIME DIRECTIVES.

Homegrown Martians had traditionally been in shorter supply, however, until "Valles Marineris" paid them a visit. The only catch? Captain Pike and his USS Enterprise crew have to travel a mere 65 million years back in time to say hi.

There's something undeniably delicious (though not, luckily, the crew) about Una Chin-Riley (Rebecca Romijn), La'an Noonien-Singh (Christina Chong) and Erica Ortegas (Melissa Navia) getting to visit the real Jurassic Park (technically Cretaceous Park) on an away mission to recover the iridium they need to repair an Enterprise stricken by its accidental trip through a quantum entangled spatial anomaly.

In the tradition of "Planet of the Apes", it turns out that this particular third rock from the sun was Earth all along. It also, according to star Rebecca Romijn, features an actual puppet from the original "Jurassic Park", and gives La'an that rare opportunity to punch a dinosaur in the face. That's definitely one to tell the grandkids — assuming, of course, you can avoid stepping on a bug, unleashing a butterfly effect, and preventing them (and the entire human race, for that matter) from ever being born.

But it's no coincidence that Pike has a copy of Edgar Rice Burroughs' "A Princess of Mars" on his bookshelf, because it's what happens in orbit that makes this episode such a pulpy sci-fi joy.

Although Battle Commander Cassell (Saffron Burrows) and her crew have the familiar, human-esque appearance of most "Star Trek" aliens, Martian evolution has got them there millions of years before Vulcans, Klingons, and the rest become top dogs in the galaxy. (Spock notes that Martian DNA is present in many modern-day species, though it's unclear how their family tree aligns with the "Progenitor" origin story of "TNG"'s "The Chase".)

These technologically advanced Martians are embroiled in a bloody ongoing war with a "Starship Troopers"-adjacent arachnid species known as the Dol'Drm, who call the fifth planet of the Sol System home. Science purists will note that this strange new world is not the famously gaseous Jupiter, but an extra, science textbook-rewriting ball of rock located roughly where the Asteroid Belt is now.

Unfortunately, once Cassell has sneaked a peek at a future where her "homeworld is a barren red wasteland", she's in no mood to listen to Federation lectures about finding diplomatic solutions. She subsequently steals some of the Enterprise's antimatter and fashions a makeshift weapon of mass destruction to eliminate the Dol'Drm once and for all. But the shockwaves of this cataclysmic blast will stretch far beyond the fifth planet.

Spock confirms that many of the fragments left behind by the obliteration of the Dol'Drm homeworld will form the Asteroid Belt, essentially a riff on the so-called "Disruption Hypothesis" of the belt's origins.

Originally postulated by German astronomer Heinrich Wilhelm Matthias Olbers in the early 19th century, the theory suggested that a rocky planet, roughly the size of our Moon, existed between the orbits of Mars and Jupiter.

It was the destruction of this world (by means unknown, though we doubt anyone suggested an antimatter explosion) that led to the formation of the belt. The hypothesis is now largely discredited — current scientific thinking suggests that the belt is the result of dust and rock coalescing due to gravity — but it's a fun revisionist spin on old scientific ideas.

And the Enterprise's involvement in the Solar System's origin story stretches even further. The gravimetric shift caused by the absence of the Dol'Drm planet shifts Mars' orbit, making it too cold to support life. It also launches arguably the most famous asteroid in history, the Chicxulub meteorite, on a collision course with Earth, wiping out the dinosaurs, kickstarting the Cenozoic Era, and sending the planet on an evolutionary journey that will eventually lead to, well, us.

When it comes to interfering with past events, the implications are rather larger than Scotty passing on the formula for yet-to-be-invented transparent aluminum in "Star Trek IV: The Voyage Home". Even the Borg meddling with a few centuries of history in "First Contact" is small fry next to killing off the dinosaurs.

The intriguing twist here, of course, is that humanity's existence is briefly on a knife-edge, as Pike makes the biggest decision of his (or, indeed, anyone's) life. Standard Starfleet protocol would usually dictate that the Enterprise intervene to prevent the Dol'Drm being destroyed by stolen Federation technology, but its commanding officer sees the bigger picture.

What if the Enterprise was always meant to be there? What if the human race only exists because the ship has gone back in time to answer its own 65-million-year-old Mayday? "In our future there is no fifth planet," he reasons, before allowing the Martians to deliver their deadly payload.

It's a wonderful "what if" that puts 65 million years of history in one man's hands. Indeed, you could tie yourself in knots with all that timey-wimey stuff, but the episode is so much pulpy fun that you barely notice the unbearable weight of those existential dilemmas. Dinosaurs, Martians and an origin story for the human race? What more could you want from a season opener?

New episodes of "Star Trek: Strange New Worlds" debut on Paramount+ on Thursdays.
