They discovered a new type of cosmic explosion that exceeds almost all previously known supernovae in terms of luminosity. This explosion became brighter than 100 billion suns in 10 days and then disappeared.
Researchers at Queen’s University Belfast, led by astrophysicist Matt Nicoll, claim that these are a completely new class of explosions that they call Luminous Flash Coolers.
They used the ATLAS network of telescopes located in Hawaii, Chile and South Africa to detect this phenomenon in a galaxy full of Sun-like stars.
This explosion occurred in a huge red galaxy 2 billion light years away from us. Archival data allowed scientists to find two similar objects, one from 2009 and the second from 2020.
