As it approaches Earth on December 19, scientists and amateur astronomers prepare for unprecedented observation opportunities that may reveal more about this mysterious object's true nature.
Record-Breaking Black Hole Flare: Supermassive Cosmic Beast Devours Massive Star 11 Billion Light-Years Away

Astronomers have observed the most powerful flare ever detected from a supermassive black hole located 11 billion light-years from Earth. This unprecedented cosmic event, 10 trillion times brighter than our sun, occurred when a black hole 300 million times more massive than the sun completely destroyed and consumed a massive star that wandered too close to its immense gravitational field. The ongoing phenomenon, first peaking in June 2018, is providing valuable insights into extreme astrophysical processes.
