Summary

Story summary

The largest and most distant black hole flare was detected from galaxy J2245+3743.
The galaxy is about 10 billion light-years away.
The flare began when a massive star was torn apart near the black hole, reaching 30 times the brightness of earlier flares and releasing energy equivalent to 10 trillion suns.
The tidal disruption event has been ongoing since 2018 and may reveal how supermassive black holes interact with stars.

History

Historical Context

The study of black holes began with the discovery of Cygnus X-1 in 1971, providing strong evidence for their existence. By 2018, astronomers observed a tidal disruption event in galaxy J2245+3743, where a star was torn apart by a supermassive black hole, emitting energy equivalent to 10 trillion suns. This highlights ongoing research into black hole dynamics and their role in cosmic evolution.
