Astronomers tracked a star in Andromeda as it dimmed and vanished without the usual fiery explosion, offering rare clues to how black holes form.

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

Astronomers watching the Andromeda Galaxy have now seen something they had only theorized before: a massive star that simply vanished, apparently collapsing straight into a black hole instead of ...

In 2014, a NASA telescope observed as the infrared light emitted by a massive star in the Andromeda galaxy gradually grew brighter. The star glowed more intensely with infrared light for around three ...

A massive star in the nearby Andromeda galaxy has simply disappeared. Some astronomers believe that it's collapsed in on ...

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 ...

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

Astronomers have caught a massive star in the Andromeda Galaxy quietly dying, collapsing into a black hole without producing a supernova, leaving behind little more than a fading trace. The findings ...

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 ...

Astronomers have caught a massive star in the Andromeda Galaxy quietly dying, collapsing into a black hole without producing a supernova, leaving ...

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 ...

NASA’s NEOWISE archival data tracks a massive star in Andromeda fading quietly into a black hole, providing detailed observations of stellar collapse and gas expulsion from 2005 to 2023.
