Brown dwarfs aren’t quite stars and aren’t quite planets, and a new study suggests there might be more of them lurking in our galaxy than…
The NASA/ESA/CSA James Webb Space Telescope has successfully completed its final tests and is being prepared for shipment to its launch site at Europe’s Spaceport in French…
The Bernese theoretical astrophysicist Kevin Heng has achieved a rare feat: On paper, he has derived novel solutions to an old mathematical problem needed to…
The Sun has a new neighbor that was hiding in plain twilight. An asteroid that orbits the Sun in just 113 days—the shortest known orbital…
