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

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

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 ...

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 ...

Nearly 4.5 million years ago, two enormous, blazing stars swung close to the solar system. They did not touch the sun, but they came close enough to leave a permanent mark on the thin mist of gas that ...

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 ...

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