Perseverance Watched Earth Disappear Behind Mars’ Moon Phobos

From the rim of Jezero Crater, Earth is only a bright point in the sky. On July 2, NASA’s Perseverance rover watched that point vanish behind Phobos, Mars’ larger moon, and recorded the event with its Mastcam-Z camera. The sequence is the first time humanity has observed Earth disappearing behind an object from the surface […]

NASA’s Lunar Test Facility Is Trying to Keep Moon Dust Out of Artemis Hardware

Moon dust looks soft in photographs, but it is a difficult material for machines and people. The grains are sharp, abrasive and electrically clingy. NASA engineers at Johnson Space Center are using a dedicated test facility to find out how tools, joints and spacesuits will cope with it before Artemis astronauts return to the lunar […]

NASA Is Testing the Antennas for Its Next Mars Aircraft

NASA is testing the communications and radar hardware for a proposed Mars aircraft mission called SkyFall. The project is still on Earth, but its engineers are working through the details that would allow three small aircraft to fly in the thin Martian atmosphere and send useful data back to a rover or an orbiter. A […]

NASA’s PREFIRE Satellites Show How the Poles Trade Heat With Space

At Earth’s poles, much of the heat leaving the planet is invisible to human eyes. NASA’s two PREFIRE CubeSats are measuring that far-infrared energy directly, and a new animation built from two complete seasonal cycles shows just how differently the Arctic and Antarctic warm and cool. The Polar Radiant Energy in the Far-InfraRed Experiment began […]

Did Neanderthals and Modern Humans Share a Culture for 20,000 Years?

Neanderthals and modern humans did not simply occupy the same landscape and disappear from one another’s story. A study of Üçağızlı II Cave in southern Türkiye points to a longer period of cultural continuity in the northern Levant, where stone tools, shell ornaments and other remains appear across a sequence spanning more than 20,000 years. […]

A Magnetar May Have Bent Empty Space—NASA’s IXPE Tests a 90-Year-Old Prediction

Empty space is not completely empty in the equations of quantum physics. Under an ordinary magnetic field, that distinction is impossible to notice. Near a magnetar—a neutron star with a magnetic field trillions of times stronger than Earth’s—space itself can alter the way light travels. NASA’s Imaging X-ray Polarimetry Explorer (IXPE) has measured unusually strong […]

NASA’s PUNCH Mission Cut Solar-Storm Arrival Uncertainty to 30 Minutes

Forecasting a solar storm is a little like watching a wave leave a distant coast and trying to guess when it will reach the beach. Scientists can see a coronal mass ejection (CME) leave the Sun, but its speed and shape can change as it crosses space. By the time it reaches Earth, the warning […]

A Rare Iron Age Marsh Fort Is Being Excavated Again After 40 Years

Archaeologists have returned to a rare Iron Age fort in Shropshire that sits in a wetland landscape rather than on a hill. The University of Birmingham has begun a new, ten-year project at Wall Camp near Telford, reopening a site that had not seen a major excavation since the 1980s. The first three-week season took […]

How Radiocarbon Dating Works—and What It Can Actually Tell Us

Radiocarbon dating is one of archaeology’s most useful tools, but it is often described as if a laboratory can place an exact year on any ancient object. The method is narrower and more interesting than that. It measures the remaining carbon-14 in material that was once alive, then uses calibration and archaeological context to estimate […]

Why Do Stars Twinkle While Planets Usually Look Steady?

Stars do not actually switch their lights on and off when they twinkle. The flicker happens between the star and your eyes, as its light passes through Earth’s moving atmosphere. Planets are affected by the same air, but they usually look steadier because their light arrives from a small disk rather than a single point. […]

The Oort Cloud: The Distant Shell of Comets We Have Never Seen Directly

The Oort Cloud is one of the strangest places in the Solar System because it has never been seen directly. Astronomers infer its existence from the paths of long-period comets: icy bodies that spend most of their lives in deep space and only occasionally fall toward the Sun. NASA describes the Oort Cloud as a […]

Cuneiform Tablets and Destruction Layers Reconstruct a Mesopotamian Siege

At Kurd Qaburstan in northern Mesopotamia, archaeologists are finding the kind of evidence that allows a destroyed city to be read from several directions at once. Cuneiform tablets, administrative sealings, a fortified wall and human remains are appearing together in layers associated with the ancient city of Qabra. The project, led by researchers from the […]

Jerusalem’s 2,800-Year-Old Dam Shows How Judah Managed Drought and Flash Floods

Jerusalem’s ancient water system was not only about finding a spring. It was about controlling what happened when the water came too quickly and when the rain failed to arrive at all. A new study has dated a large dam near the Siloam Pool to roughly 805–795 BCE, during the period when the kingdom of […]

Three Roman Desert Camps May Reveal a Hidden Campaign Against Nabataea

The desert north of Arabia has kept a Roman military story out of sight for almost two thousand years. Now three angular traces in the landscape are giving archaeologists a possible route to follow. Researchers working with satellite imagery have identified three Roman marching camps in the Harrat al-Shaam region, close to the ancient frontier […]

Webb Found a Hidden Planet in Beta Pictoris By Reading Its Atmosphere

Astronomers have found a third giant planet around Beta Pictoris, one of the best-known young planetary systems near Earth. The discovery is striking because the planet was not first picked out as a bright dot in a telescope image. NASA’s James Webb Space Telescope found it in the spectrum of light coming from the system: […]

NASA Is Targeting an August Launch for Roman. Here’s What the Telescope Will See

NASA is currently targeting August 30 for the launch of the Nancy Grace Roman Space Telescope from Florida. The date can move, as launch dates do, but the mission is close enough to the pad that its central idea deserves a clear look: Roman will survey huge stretches of the universe in one exposure, gathering […]

LiDAR Suggests More Than 20,000 Ancient Earthworks in the Amazon

A laser survey of southwestern Amazonia has changed the scale of an old archaeological question. The aircraft did not reveal a hidden stone city, and it did not count 20,000 monuments one by one. What it did reveal was a dense pattern of ancient earthworks beneath the forest canopy—enough for the research team to estimate […]

NASA’s PUNCH Mission Predicted a Solar Storm Arrival Within 30 Minutes

NASA says a new four-spacecraft mission has completed an early test that could make one of the hardest parts of space-weather forecasting much more precise: estimating when a solar eruption will reach Earth. In a proof-of-concept exercise announced on August 4, NASA’s PUNCH mission used continuous images of a coronal mass ejection, or CME, to […]

A Near-Earth Object Called an Asteroid for Decades Turns Out to Be a Comet

For nearly three decades, 1998 SH2 looked like a fairly ordinary near-Earth asteroid. It was discovered in 1998, catalogued, and followed through a 4½-year orbit around the Sun. Then, during a close but safe pass by Earth in August 2025, its motion refused to match the path astronomers had calculated. The explanation, announced by NASA […]

A Black Hole Far from Its Galaxy’s Center Was Caught Tearing Apart a Star

A star being torn apart by a black hole is already an unusual sight. In this case, the black hole was in an even stranger place: more than 30,000 light-years from the center of the galaxy that appears to host it. NASA’s Neil Gehrels Swift Observatory helped confirm the event after an automated survey spotted […]
