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 ...

SN 2024abfl, a low-luminosity Type IIP supernova in the galaxy NGC 2146. This rare find is shedding new light on how stars ...

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 ...

Several telescopes used to observe the supernova SN Zwicky which was magnified nearly 25 times by a foreground galaxy acting ...

A mysterious cosmic explosion linked to gravitational waves may reveal a previously unknown type of supernova event - a ...

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

An international team of astronomers has conducted photometric and spectroscopic observations of a recently discovered ...

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

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 that theorized that when a star underwent direct collapse, it would leave ...
