Astronomers have discovered the first radio signals from a unique category of dying stars, called Type Ibn supernovae, and these signals offer new insights into how massive stars meet their demise.

Artist's impression of a supernova. By ESO/M. Kornmesser/Wikimedia Commons, CC BY My hypothesis is that remnants of a supernova – an exploding star – had an impact on the Earth’s past climate, causing ...

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 ...

The James Webb Space Telescope has picked up the light from a massive star that exploded about a billion years after the ...

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 ...
