supernova

A supernova that erupted when a massive star died could have destroyed our infant solar system — if it weren't protected by a cocoon of molecular gas.

The observation that the universe appears to run slower in the past was made by scrutinizing the light emitted by gigantic quasars.

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.
