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

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

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

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 obtained visual evidence that a star met its end by detonating twice. By studying the ...

Type I supernova: A star accumulates matter from a nearby neighbor until a runaway nuclear reaction ignites. Type II supernova: A star runs out of nuclear fuel and collapses under its own gravity.

This all ultimately gives rise to a thermonuclear explosion called a Type 1a supernova. An illustration shows a white dwarf stealing matter from a companion star. (Image credit: NASA's Goddard ...

A supernova is the catastrophic explosion of a star. Thermonuclear supernovae, in particular, signal the complete destruction of a white dwarf star, leaving nothing behind. At least that’s what ...

“ENTs are different beasts,” study lead author and astronomer Jason Hinkle explained in an accompanying statement. “Not only are ENTs far brighter than normal tidal disruption events, but they remain ...

How do supernovas occur? This is what a recent study published in Nature hopes to address as a team of researchers examine how recent radio wave emissions have not only helped astronomers identify the ...

Astronomers at the University of Hawaii uncovered black hole events so packed with energy, they were the biggest explosions ...

A composite image shows the remains of supernova SN 1181, a cataclysmic collision of two stars. The spherical nebula has at its center a hot white dwarf, or "zombie star," left behind after the ...
