It's just a matter of time before a dead star reignites in space 3,000 light years away. And you'll be able to see it with the naked eye despite the distance. Astronomers say when the explosion ...

Earth sits in a harsh galaxy filled with high-energy particles that can strip atmospheres, scramble DNA, and sterilize worlds ...

Gold, uranium, and other heavy elements on Earth did not form here. They were born in the violent deaths of massive stars and ...

Dark matter, if it exists, is probably in the latter category. If hypothetical weakly interacting massive particles (WIMPs) are real, their collisions with regular matter may have left fossil traces ...

What can imaging supernovae (plural for supernova) explosions teach astronomers about their behavior and physical characteristics? This is what a recent study published in Nature Astronomy hopes to ...

NEW YORK – Scientists for the first time have spotted the insides of a dying star as it exploded, offering a rare peek into stellar evolution. Stars can live for millions to trillions of years until ...

NASA plans to launch a mini satellite into Earth's orbit that could revolutionize astronomy as we know it.

The comet will come much closer to Jupiter in March, zipping within 33 million miles. It will be the mid-2030s before it ...

Earth may owe some of its properties to a nearby star that blew up just as the solar system was forming. This pattern, which saw a supernova bubble envelop the sun and shower it with cosmic rays, may ...
