Scientists suggested that a star that disappeared in the Andromeda Galaxy had an unsuccessful supernova.
When massive stars reach the end of their life cycle, they collapse on themselves in an explosion called supernova, leaving behind a black hole or neutron star.
The star named M31-2014-DS1 in Andromeda, a neighbor of the Milky Way about 2.5 light years away, started to lose its brightness starting from 2016 and became invisible in 2023. A newly formed dust cloud was observed around it, but no evidence of an explosion was found. Researchers noted that this star bears similarities to another star called N6946-BH1, which is thought to have undergone a failed supernova.
Astrophysicist Morgan Fraser said the observations supported the possibility of failed supernovae, but dust clouds could obscure the stars.
