In 1181 AD, a bright "guest star" was observed to linger in the sky for around six months. Nearly 850 years later, the likely remnants of this event were rediscovered and tentatively linked to the ...

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 ...

This is an artist's impression of a supernova. Aaron Geller (Northwestern University) A supernova at least twice as bright and energetic, and likely much more massive than any yet recorded has been ...

A first-of-its-kind, animated map has revealed fresh secrets about a mysterious, flowering "zombie star" lurking in the remnant of a supernova that lit up Earth's skies more than 800 years ago. The ...

A scintillating spiral galaxy that played host to two supernova explosions in the past 30 years takes center stage in a new image captured by a telescope in Chile's high desert. The galaxy NGC 1187 is ...

You might think of a star as a mass of incandescent gas, a gigantic nuclear furnace where hydrogen is turned into helium at a temperature of millions of degrees. But researchers recently reported that ...
