Scientists watched as a star, once one of the brightest in the Andromeda galaxy, simply winked out of existence. They have a ...

Astronomers combing through years of images collected by the NEOWISE mission have found the clearest known evidence of a star converting directly to a black hole, without passing through the supernova ...

Only one such event had been documented previously, a star recorded vanishing around 2010 in a galaxy 22 million light-years ...

A deep space photographer spent months photographing the Crab Nebula and found his composite image, when compared with the 1999 image from the Hubble Space Telescope, shows the supernova's expansion.

The team discovered the star by analyzing archival data from NASA’s NEOWISE mission. They used a prediction from the 1970s that theorized that when a star underwent direct collapse, it would leave ...

A “disappearing” star in the Andromeda galaxy is the closest and best candidate for a newborn black hole that astronomers have ever seen ...

"This provides observational evidence of black hole formation in real time, suggests that many black holes may form without ...

Astronomers have watched a dying star fail to explode as a supernova, instead collapsing into a black hole. The remarkable sighting is the most complete observational record ever made of a star's ...

Merger of two neutron stars in the aftermath of a supernova may have been observed for the first time, though questions ...
