Seeing a Stellar Collision Produce a Supernova for the First Time - The Cosmic Companion 7 Sept. 2021
A core collapse supernova - previously postulated but never before seen, may have just been witnessed by astronomers...
Watching a stellar collision produce a supernova – a never-before seen sight!
In a star-forming dwarf galaxy 480 million light years from Earth, an ultra-dense stellar remnant — likely a black hole or neutron star — collided with its stellar companion.
Astronomers on Earth have long postulated that such collisions could take place in certain binary star systems.
“Theorists had predicted that this could happen, but this is the first time we’ve actually seen such an event,” said Dillon Dong, a graduate student at Caltech and lead author on a paper reporting the discovery, published in the journal Science.
