Overview

• The largest cosmic explosion ever observed, named AT2021lwx, was first detected in 2020 and has been continuously erupting for over three years.
• The explosion is located eight billion light years from Earth and is 100 times larger than our solar system, emitting a brightness two trillion times that of the sun.
• The cause of the massive explosion is believed to be a supermassive black hole violently disrupting an enormous gas cloud, though the exact mechanism is still unknown.
• The discovery of such a powerful and long-lasting cosmic event suggests there are still unknown astronomical phenomena in the universe left to uncover.
• Further study of AT2021lwx could provide insights into galaxy formation and the behavior of supermassive black holes.
