Some 1.3 billion years ago, when multicellular organisms were just emerging on Earth and life was still confined to the ocean, two behemoth black holes smashed together in a far-flung galaxy. The collision was so powerful that it jolted the universe, creating a ripple in the fabric of space-time that traveled across the cosmos atContinue reading "How gravitational waves transformed our universe"

Star formation in the nearby Andromeda Galaxy (M31) has been slowing down over the last 500 million years, according to a new study using Hubble Space Telescope data.  The study was published July 27, 2026, in The Astrophysical Journal. Lead author Tobin Wainer, an astronomer at the University of Washington, and his team used dataContinue reading "Andromeda’s star formation is slowing down"

Astrophotography tends to blur the boundary between science and art. The incredible images from Hubble and JWST, for example, captivate us as much for their aesthetic beauty as for their data. Recently, a photography student blurred those lines even further, taking the concept of capturing the cosmos quite literally by creating images from film’s interactionContinue reading "How one student captured the universe without light"

Earth’s orbit is getting crowded. About 16,000 satellites currently circle our planet, supporting everything from GPS navigation and weather forecasting to banking, emergency services and internet communications. Dozens more are launched every few weeks. Some estimates suggest the total number of satellites could exceed 100,000 within this decade, with more conservative estimates landing on up to 60,000 satellites byContinue reading "There are already 16,000 satellites in Earth’s orbit.

Nearly 400 days and a billion kilometers after leaving Earth, China’s Tianwen-2 spacecraft has arrived at its target: the near-Earth asteroid 469219 Kamoʻoalewa, also known as 2016 HO3. And the mission’s first photo of the rock has already had scientific impact, reopening an ongoing investigation over whether Kamoʻoalewa began as a chunk of the Moon.Continue reading "Tianwen-2 arrives at target asteroid Kamoʻoalewa"

When massive stars die, they explode, leaving behind supernova remnants. Given how common binary star systems are — more than half the stars in our galaxy have a companion — it stands to reason that paired supernova remnants would also be common. But astronomers have never found one. Now, hiding in the bright shine ofContinue reading "Is this the first known binary system to produce two supernova remnants?"
