Astronomers have spotted the most powerful supernova in human history.
The record-breaking cosmic explosion was 570 billion times brighter than the sun and about 200 times more powerful than a typical supernova, scientists said.
The blast – known as ASASSN-15lh- is thought to be an example of a “superluminous supernova,” a recently-discovered type of explosion unleashed by certain stars when they die.
But space experts are at a loss about which stars might be responsible for such an extreme event.
Astronomer Subo Dong said: “ASASSN-15lh is the most powerful supernova discovered in human history.
“The explosion’s mechanism and power source remain shrouded in mystery because all known theories meet serious challenges in explaining the immense amount of energy ASASSN-15lh has radiated.
