It took about 50 exploding stars to upend cosmology. Researchers mapped and measured light from Type Ia supernovae, the ...

The two objects make for a strange pair. Unlike Betelgeuse, which is approaching the end of its life, the blue-white ...

MUSE allows astronomers to map the distribution of different chemical elements, displayed here in different colours. Calcium is shown in blue, and it is arranged in two concentric shells. These two ...

For the first time, astronomers have spotted a star that exploded not once, but twice. A new image of a roughly 300-year-old supernova provides visual evidence that some dying stars undergo a double ...

A newly discovered supernova can be watched as it develops in real-time online and for free. The event will kick off at 6:00 p.m. EDT (2200 GMT) on Thursday, May 25.

An unusual star system created more of a fizz and less of a bang when it exploded in a supernova. The “ultra-stripped” supernova led researchers to discover the two stars 11,000 light-years ...

Pictures of a distant supernova remnant show two concentric rings, providing clear evidence that exploding white dwarf stars ...

The explosion of a star, called a supernova, is an immensely violent event. It usually involves a star more than eight times ...

Astronomers have, for the first time, witnessed a star meeting a dramatic end by exploding twice. In a study published in ...

The supernova, named SN 2023ixf, is located 21 million light-years away. It should remain visible with the aid of a telescope for at least a few months, astronomers said.
