Earth sits in a harsh galaxy filled with high-energy particles that can strip atmospheres, scramble DNA, and sterilize worlds, yet life here has persisted for billions of years. New research suggests ...

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 ...

Astronomers find galaxy Y1, a young star-forming region, revealing extreme heat just 600 million years after the Big Bang.

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 ...

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’s the link between an exploding star, climate change and human evolution? Francis Thackeray, who has researched ancient environments and fossils for many years, sets out his ideas about what ...
