Astronomers Observe Star's Silent Collapse into Black Hole in Andromeda Galaxy
Astronomers have observed a massive star, designated M31-2014-DS1, in the Andromeda Galaxy collapsing directly into a black hole without a preceding supernova explosion. This event is the first clear documented case of such a silent collapse, challenging traditional models of stellar death that typically involve a supernova phase before black hole formation. The observation provides new insights into the processes of stellar evolution and death.
The research involved astronomers including Kishalay De from the Simons Foundation's Flatiron Institute and utilized data from NASA's NEOWISE mission. Observations were conducted from New Mexico, United States. This finding suggests that some massive stars may bypass the supernova stage entirely when forming black holes, offering a new perspective on how black holes can form silently in galaxies like Andromeda.
