A recently discovered type of stellar explosion might fit right in among the spectrum from regular supernovae to massive gamma-ray bursts.
Astronomers have identified the origin of a mysterious flash that occurred three years ago.
Some 10 million years ago, dying stars cleared a giant cavity in space and ultimately inspired a new generation of star formation.
One of the most luminous supernovae ever discovered provides evidence that such extremely bright explosions require exotic sources.
Astronomers can't agree on what kind of strange stellar death created a brilliant source dubbed "the Cow."
In 2016 an amateur astronomer was testing his camera — and captured the first flash of a supernova.
Between the discovery of the new comet ASASSN1 and two stellar explosions, there's a lot happening in the sky this week. Take your telescope out and see what all the excitement's about.
Astronomers may have watched a star collapse directly into a black hole — minus the supernova. The failed supernova could help understand how stars die.
