A massive star brightened in infrared light, then vanished without exploding. Astronomers uncovered the quiet birth of a ...

Astronomers watched a massive star in the Andromeda Galaxy vanish over a decade, providing rare evidence of a "failed supernova" forming a black hole without exploding.

In 2014, a NASA telescope observed that 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 ...

A massive star 2.5 million light-years away simply vanished — and astronomers now know why. Instead of exploding in a supernova, it quietly collapsed into a black hole, shedding its outer layers in a ...

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 ...

Ready to build thicker, stronger arms? These expert-approved exercises are designed to maximize bicep definition, strength, and overall upper-body power.

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.

Only one such event had been documented previously, a star recorded vanishing around 2010 in a galaxy 22 million light-years away. Now, by carefully looking over archival observations of the Andromeda ...

The team discovered the star by analyzing archival data from NASA’s NEOWISE mission. They used a prediction from the 1970s ...

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 ...

One of the brightest stars in the Andromeda galaxy has disappeared without the explosion astronomers expected. Instead, they ...
