#Repost///@james.webb.telescope.official: Astronomers have discovered a new class of cosmic explosion brighter than 100 billion suns in a massive, red galaxy two billion light-years away. Dubbed “Luminous Fast Coolers”, this new class of extreme cosmic explosion is incredibly rare and unbelievably bright. A supernova usually reaches its peak brightness in 20 days and then fades over months. But Luminous Fast Coolers reach to the peak brightness of 100 billion suns in only a week and then then fade away to only 1% of its peak brightness in only 15 days. The explosion do not fit the profile of any known supernova. Thus the researchers combed through archival telescope surveys, looking for objects with a similar brightness and lifespan. They ultimately uncovered two other objects one from a 2009 survey, and the second from 2020 with similar properties to the newly detected blast. The most plausible explanation seems to be a black hole colliding with a star. However, this explanation doesn't quite fit; when black holes rip material away from passing stars in interactions known as tidal disruption events, they release bright X-ray emissions and none of the LFCs identified here showed any X-ray emissions. What exactly are LFCs, then? For now, Astronomers can only speculate.
