In 1181 AD, a bright "guest star" was observed to linger in the sky for around six months. Nearly 850 years later, the likely ...

SN2021yfj is a new kind of supernova, challenging our understanding of stellar evolution. Its progenitor lost its outer shells well before the supernova happened and only consisted of its ...

Axions are the most likely candidate for enigmatic dark matter that dominates the universe. Astrophysicists are searching for evidence of high-mass axions produced during supernovae. Scientists ...

Kepler's supernova remnant is extremely exciting for astronomers – a rare example of a supernova for which we have a clear kick-off timeline, dating back more than 400 years. It's also just 20,000 ...

Astronomers have observed what they are calling a new type of supernova, which has provided an unparalleled glimpse into what happens deep within a star just before it explodes. A study detailing the ...

Scientists have detected the most distant supernova ever seen, exploding when the universe was less than a billion years old. The event was first signaled by a gamma-ray burst and later confirmed ...

A new animated map sheds light on the superhot "zombie star" at the heart of a nebula leftover from a distant supernova witnessed by astronomers in 1181. The remains of the stellar explosion are ...
