A supernova explosion occurred on July 4, 1054, resulting from the death of a star estimated to be nine to eleven times the ...

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

For the first time, astronomers have obtained visual evidence that a star met its end by detonating twice. By studying the ...

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

Researchers have used machine learning to dramatically speed up the processing time when simulating galaxy evolution coupled with supernova explosion. This approach could help us understand the ...

"This tangible evidence of a double detonation not only contributes towards solving a long-standing mystery, but also offers ...

Astronomers have finally caught a dying star in space going out with a bang — and then another bang. The new photographic ...

Astronomers studying the remnant SNR 0509-67.5 have finally caught a white dwarf in the act of a rare “double-detonation” supernova, where an initial helium blast on the star’s surface triggers a ...

An explosion captured in a new image could help astronomers to better understand the "standard candles" at the center of a ...

For years, scientists have suspected that stars can meet their doom by a one-two punch of back-to-back explosions — but ...
