Mysterious bright blue cosmic blasts triggered by black holes shredding stars, scientists say. 'It's definitely not just an exploding star.'

By Robert Lea published

"The sheer amount of radiated energy from these bursts is so large that you can't power them with a core collapse stellar explosion — or any other type of normal stellar explosion."

Black Holes
Illustration of a hypothesized event known as a superkilonova. A massive star explodes in a supernova (left), which generates elements like carbon and iron. In the aftermath, two neutron stars are born (middle), at least one of which is believed to be less massive than our Sun. The neutron stars spiral together, sending gravitational waves rippling through the cosmos, before merging in a dramatic kilonova (right). Kilonovae seed the universe with the heaviest elements, such as gold at platinum, which glow with red light.

Astronomers may have spotted the 1st known 'superkilonova' double star explosion

"We do not know with certainty that we found a superkilonova, but the event nevertheless is eye-opening."
