supernova

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).

Signatures of neutrinos, or ghostly particles that rarely interact with others, were tentatively spotted in the Large Hadron Collider in 2021. Now, physicists have confirmed they are real.

NASA's James Webb Space Telescope has snapped a picture of WR 124, a rare Wolf-Mayet star 30 times the size of our sun, ejecting a luminous cloud of cosmic dust.
