supernova

SN 2023ixf is the closest supernova to Earth in more than a decade — and the perfect excuse for intelligent aliens to get our attention, new SETI research suggests.

Astronomers discovered a new population of ultra-fast-moving stars, including the fastest 'runaway' star ever seen in our galaxy.

Carl Sagan famously proclaimed that humans are 'made of star stuff'. Here's what he meant — and why it's true.

A new system that uses subatomic particles produced high in Earth's atmosphere could provide a view inside volcanoes and help locate people trapped beneath rubble.

The gravity of a galaxy two-and-a-half billion light-years away has acted like a cosmic magnifying glass to amplify the light of a distant exploding white dwarf.

A newly discovered supernova can be watched as it develops in real-time online and for free. The livestream will begin at 6:30 p.m. EDT (2230 GMT) on Friday, May 26.

After showing up five times in Hubble images, a 'reappearing supernova' is helping scientists solve one of astronomy's biggest mysteries.

Astronomers have spotted a giant explosion releasing over 100 times more energy than the sun will release across its entire lifetime. A monster black hole is likely to blame.

New James Webb Space Telescope images reveal the grisly past of Cassiopeia A, the youngest known supernova remnant in the Milky Way.

A bizarre object called "the Cow" is the flattest explosion ever detected, and the first example of a rare phenomenon called a fast blue optical transient (FBOT).
