A new explanation for the solar system's radioactive elements suggests Earth-like planets might be found orbiting up to 50 ...

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 ...

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 ...

Dust littered the early universe and seeded the formation of rocky planets such as the Earth. But where, exactly, most of the celestial grit came from was uncertain until now. Astronomers have found ...

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 ...

Francis Thackeray has received funding from the National Research Foundation. Global cooling that happened millions of years ago was thought to be the result of ocean currents. He suggests instead it ...
