Betelgeuse, the red supergiant star marking Orion’s left shoulder, will one day explode as a supernova bright enough to see ...

Astronomers have found evidence that two closely associated supernova remnants were probably formed by both stars in a binary ...

A supernova remnant is supposed to be a rough neighborhood for a newborn star. Shock waves rip through space at thousands of kilometers per second.

A long time ago, in a galaxy far, far away, a massive star collapsed, triggering a supernova explosion so bright it could be seen across the universe. When the light reached Earth, telescopes around ...

The Jellyfish Nebula, one of the best-studied supernova remnants in our galaxy, may have been hiding a sibling this whole ...

The star that formed the Jellyfish nebula may have had a partner star that exploded 100,000 years earlier, according to ...

An international team of astronomers has performed follow-up observations of a peculiar Type Ia supernova designated SN ...

Artist’s impression of a hot core—a warm cocoon of molecular gas surrounding a newborn star—discovered in a supernova remnant. Blue represents high-energy regions produced by the supernova explosion, ...

Earth is quietly collecting radioactive debris from an ancient stellar explosion as our Solar System drifts through a giant cloud of gas and dust between the stars. Scientists analyzing Antarctic ice ...

There are things in this Universe the human mind simply has a very hard time understanding. Like, say, a supernova explosion caused by a star reaching the end of its life, an event so massive that, ...

Astronomers used the Hubble Space Telescope to measure the expanding Crab Nebula. New images compared with older ones show gas filaments moving outwards. This ancient stellar explosion's remnant is ...

In late 1572, long before the invention of the telescope, sky-watchers looking up at the night sky saw something impossible: ...
