Astronomers Witness Largest-Ever Cosmic Explosion and Explain Its Puzzling Nature.

Astronomers have observed the largest explosion yet in space, a years-long event involving a supermassive black hole estimated to be one billion times more massive than the Sun that continues to rage. The eruption, codenamed AT2021lwx, was first recorded by ground-based telescopes in 2020. The astronomer team believes this rare event has lasted so long because the supermassive black hole at the heart of it has been feeding on matter from a gigantic gas cloud, possibly thousands of times more massive than the Sun. The team will continue to study the explosion and is planning to observe it with spacecraft such as NASA's Hubble Space Telescope or the James Webb Space Telescope to try and hunt for the galaxy housing the supermassive black hole.
