"Surprising Brightness: Most Distant Active Black Hole 'Switches On' in Record-breaking Event"

Astronomers have observed a supermassive black hole, known as J221951, undergoing a dramatic "switching on" event, resulting in one of the brightest transient events ever recorded. The cause of this event is still unknown, but it could be due to the black hole consuming a star that ventured too close and being torn apart in a process called spaghettification. Another possibility is that the black hole is transitioning from a dormant to an active state, known as an active galactic nucleus. Further monitoring is needed to determine the exact cause of this event.
