Astronomers Capture Largest Cosmic Explosion Ever Seen

Astronomers spotted, Friday, the largest cosmic explosion ever witnessed, and it’s 10 times brighter than any known exploding star or supernova, reported local news outlets.
The brightness of the explosion, called AT2021lwx, lasted for three years, while most supernovas are only bright for a few months.
Astrophysicist at the Britain’s University of Southampton and the lead author of a new study Philip Wiseman said that AT2021lwx was considered the “largest” explosion because it had released far more energy over the last three years than was produced by BOAT’s brief flash.
The event occurred nearly 8 billion light-years away from Earth when the universe was about 6 billion years old.
The luminosity of the explosion is also three times brighter than tidal disruption events when stars fall into supermassive black holes.
The Zwicky Transient Facility in California first spotted AT2021lwx during an automated sweep of the sky in 2020.
Scientists believed that AT2021lwx is the result of a vast cloud of gas plunging into the inescapable mouth of a supermassive black hole.
