The LUX-ZEPLIN experiment recorded one 248 keV nuclear recoil event at 2.6-sigma significance in its South Dakota xenon detector, its most compelling dark matter hint yet.
NASA's Nancy Grace Roman Space Telescope activated its Coronagraph Instrument on September 1, 2026, beginning months of tests before it directly images giant exoplanets and dusty disks.
Archival Subaru Telescope images showed comet 28P/Neujmin brightening near opposition the way a high-reflectance asteroid would, despite having the surface color of a dark, low-reflectance one.
NASA's Neil Gehrels Swift Observatory resumed two of its three science instruments Aug. 26 after a commercial rescue mission to boost its orbit fell through.
NASA's Nancy Grace Roman Space Telescope launched Aug. 30 aboard a Falcon Heavy rocket, beginning a three month journey toward a vantage point one million miles from Earth.
NASA's Swift Observatory confirmed a supermassive black hole shredding a star 30,000 light-years from its host galaxy's core, the most distant such event yet found.
UC Riverside astrophysicist Stephen Kane found Venus appears to rotate 60 times faster than it truly does because astronomers were measuring atmospheric winds, not planetary rotation.
NASA's Perseverance rover captured the first-ever observation from another planet of Earth disappearing behind an object, the Martian moon Phobos.
A four-telescope composite of the Tarantula Nebula reveals up to half its hot gas is leaking out through the star-forming region's shell walls.
A new Chandra, Webb, and Hubble composite of the Tarantula Nebula helped astronomers determine that up to half its hot, stellar-wind-heated gas is escaping undetected.
