Hubble telescope finds double quasar in early universe

NASA’s Hubble Space Telescope made an unexpected discovery — a pair of gravitationally bound quasars inside two merging galaxies that existed when the universe was just three billion years old.…

Webb finds water, and a new mystery, in rare main-belt comet

The NASA/ESA/CSA James Webb Space Telescope has enabled another long-sought scientific breakthrough, this time for Solar System scientists studying the origins of the water that has made life on Earth possible. This…

Laboratory solar flares reveal clues to bursts of high-energy particles from space

Simulating solar flares on a scale the size of a banana, U.S. National Science Foundation-supported researchers at Caltech have parsed out how these massive explosions blast potentially harmful energetic particles and X-rays into…

Astronomers just saw a star eat a planet—an astrophysicist on the team explains the first-of-its-kind discovery

For the first time, astronomers have captured images that show a star consuming one of its planets. The star, named ZTF SLRN-2020, is located in the Milky Way galaxy, in…

NASA’s Perseverance Images May Show Record of Wild Martian River

Years ago, scientists noticed a series of curving bands of layered rock within Jezero Crater that they dubbed “the curvilinear unit.” They could see these layers from space but are…

Stuck antenna freed on Jupiter-bound spacecraft

In this frame grab from video provided by the European Space Agency, the second stuck part of the RIME antenna deploys, seen at right leaning vertically, on a spacecraft bound…
