Astronomers have captured the first detailed images of a star beyond our Milky Way galaxy on the verge of a supernova. 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 ...

When a supernova was seen glittering in the night sky for six months in 1181, it was so bright that Chinese and Japanese astronomers recorded it as a “guest star” in the Cassiopeia constellation.

Astronomers have photographed a distant star in what appears to be its death throes, the first time such a phenomenon has ...

Betelgeuse’s future supernova won’t harm Earth, but close cosmic explosions could strip our ozone, risking life. Gamma-ray ...

To estimate how close a supernova would have to be to cause serious damage to Earth, we must first look at a supernova's destructive capabilities. When the bright star Betelgeuse explodes ...

Astrophysical explosions, encompassing events like supernovae and black hole consumptions, are becoming increasingly ...

TOKYO — When a supernova was seen glittering in the night sky for six months in 1181, it was so bright that Chinese and Japanese astronomers recorded it as a "guest star" in the Cassiopeia ...

such stars normally don’t survive a supernova’s blast, making this one a rare member of the stellar undead—a so-called zombie star. Most supernovae happen when massive stars run out of fuel ...

Andy Howell leads the supernova group at the Las Cumbres Observatory and is an adjunct professor in the Department of Physics at UC Santa Barbara. Most of his research focuses on supernovae — how they ...
