Astronomers have discovered the most powerful cosmic explosions since the Big Bang, naming them "extreme nuclear transients."

These incredibly energetic explosions occur when stars with masses at least three times greater than that of the sun are torn apart by supermassive black holes. While such events have been witnessed before, astronomers say some of the ones recently discovered are powerful enough to be classified as a new phenomenon: extreme nuclear transients (ENTs).

"We've observed stars getting ripped apart as tidal disruption events for over a decade, but these ENTs are different beasts, reaching brightnesses nearly ten times more than what we typically see," said Jason Hinkle, a researcher at the University of Hawaii's Institute for Astronomy (IfA) who led a study on these eve
