Astronomers have detected a faint radio source at the position of SN 2025ulz, the exploded star that appeared in the same patch of sky, at the same moment, as a weak gravitational-wave candidate in…

Deepayan Banik and colleagues report that a planet keeping one face permanently toward its star can end up with a night side warmer than its day side, if the starlight it receives rises and falls as…

A modeling study has taken a method built to forecast lava flows on Earth and applied it to Titan, reporting that a water-rich flow on Saturn's largest moon would run several tens of kilometers and…

Researchers led from Tohoku University have built a computer model of where formaldehyde (H₂CO) would have landed on the surface of early Mars, and it puts about ten times the global average over the…

IC 443 and W44 are among the best mapped pieces of debris in the Milky Way. Each is the expanding shell of a star that exploded, and each is driving a shock wave into a neighboring molecular cloud.…

A SpaceX Falcon 9 rocket carried four crew members toward the International Space Station at 11:10 a.m. EDT on Oct. 1, 2026, from Cape Canaveral Space Force Station in Florida. Their Dragon capsule…

Three small spacecraft funded by NASA reached orbit on Oct. 1, 2026, lifting off at 11:32 a.m. PDT from Vandenberg Space Force Base in California aboard a SpaceX Falcon 9 on the Transporter-18…

Chemists at the University of Hawaii at Manoa have made pyridine, a ring of five carbon atoms and one nitrogen, inside laboratory ice built to imitate the frozen coatings of interstellar dust grains.…

Astronomers have confirmed a planet about twice the width of Earth orbiting TOI-210, a small, cool red dwarf, once every 9.01 days. The result comes from a preprint posted to arXiv on Sept. 28 by a…

Astronomers using NASA's James Webb Space Telescope have assembled 21 young star systems whose dust appears to be the wreckage of collisions between rocky bodies, and have sorted them into two groups…

Astronomers have collected light from far earlier in cosmic history than this. What they have rarely had, that far out, is a case with enough evidence to narrow down what they are seeing. A faint dot…

An Italian startup says it has moved precise orbit determination, the job of pinning down exactly where a spacecraft is, onto the satellite itself. NaviGate, a spinoff of Sapienza University of Rome,…
