The bright binary star system V Sagittae will flare up multiple times before finally going supernova within the next 100 ...

When a massive star dies, astronomers expect a familiar chemical script: hydrogen and helium on the outside, heavier elements ...

An explosive event in the sky might soon captivate stargazers, as a research team led by the University of Turku predicts ...

XRISM’s high-precision X-ray data revealed unusually strong signatures of chlorine and potassium inside the Cassiopeia A supernova remnant. These levels are far higher than theoretical models ...

A faint, ancient flash of light detected by the James Webb Space Telescope (JWST) has broken the record for the most distant ...

Astronomers from Texas have witnessed the moment a star's surface is torn apart by a supernova, becoming oblong in the process and producing more light than the entire galaxy for an instant.

A new discovery about what happens when a supernova – an exploding star – and a black hole collide could change the way scientists understand the lives and deaths of stars. The finding was the first ...

Type Ia supernovae are critical tools in astronomy, since they all appear to explode with the same intensity, allowing us to use their brightness as a measure of distance. The distance measures ...

Astronomers have been able to establish a direct link between supernovae and the formation of black holes and neutron stars, in one of the most intriguing cosmic events ever documented. This discovery ...

Gamma-ray bursts (GRB) are some of the most perplexing phenomena in nature. Even though astronomers have detected about 15,000 of them, with a new one each day, they're still mysterious. They're the ...

"This observation also demonstrates that we can use Webb to find individual stars when the universe was only 5% of its ...
