Astronomers using data from NASA, the European Space Agency (ESA), and other observatories around the world have discovered the most energetic explosions to occur since the Big Bang 13.8 billion years ago.

That's because 80 billion lightyears from Earth, three cosmic beasts are devouring stars ten times the size of the sun. The explosions those scientists have recorded, which happened when those black holes shredded and sucked up the fabric of those stars,

Astronomers discovered a new class of cosmic explosions known as "extreme nuclear transients" that are the most powerful phenomena known, aside from the Big Bang.
