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

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 ...

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 ...

Using archival data from NASA’s NEOWISE mission along with data from other space and ground-based observatories, astronomers identified the clearest observational record yet of a massive star fading ...

Astronomers tracked a star that slowly faded instead of exploding. The quiet disappearance may reveal a hidden way black ...

WASHINGTON, Feb 12 (Reuters) - The formation of a black hole can be quite a violent event, with a massive dying star blowing up and some of its remnants collapsing to form an exceptionally dense ...

Astronomers have captured one of the clearest views ever of a massive star dying—not in a dramatic supernova explosion, but ...

It is easy to observe when stars explode in a supernova and become a black hole. It is different when they simply collapse.

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.

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 ...
