Tatooine exoplanets - or planets orbiting 2 stars - are rare. And a new study from UC Berkeley says Einstein's general theory of relativity is to blame.
A new analysis of images from the Galileo mission has revealed deposits of ammonia on Europa. It could mean a geologically active crust and habitable ocean.
Spring fireball season is now! The rate of fireballs (bright meteors) often goes up in the Northern Hemisphere by as much as 30% from February through April.
Did we just witness a black hole explode? Astronomers observed a strange particle collide with Earth that could have been the result of a black hole exploding.
Researchers simulated the conditions in Enceladus' ocean and found that a wide variety of organic molecules can easily form, increasing the chances for life.
Astronomers have discovered a possible ice-cold Earth exoplanet 146 light-years away. It might be colder than Mars, but there's a chance it's more Earth-like.
Astronomers using the Very Large Telescope might have found a massive exomoon - 40% the mass of Jupiter - orbiting a giant exoplanet 133 light-years away.
