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 ...

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 ...

An international team led by Monash University has uncovered evidence of a rare form of exploding star, helping to shed light ...

The first generation of stars that were born in the universe are a mystery. We can estimate when they existed and even how big they might have gotten, but direct evidence has been lacking. Now, JWST ...

Astrophysicists have achieved an eye-opening leap in understanding stellar death, capturing unprecedented, detailed images of two exploding stars that demonstrate these blasts are far more complicated ...

Researchers identified a "forbidden range" of black-hole masses more than 45 times the Sun's mass, where stellar-origin black holes are rare. The gap aligns with models in which such stars explode via ...
