What we know about black holes, one of the most mysterious and interesting objects in the universe, is increasing day by day. Now, scientists from the Massachusetts Institute of Technology in the USA have detected a black hole eating a black hole star. The research findings have been published in The Astrophysical Journal Letters.
Revealing an extremely rare event, this moment allows us to see a black hole swallow a star this close for the first time.
The event took place in the galaxy NGC 7392, 137 million light-years away.

Every 10,000 years, the center of a galaxy lights up when a supermassive black hole shatters a nearby star. In this astronomical phenomenon, called the “tidal disruption event,” or TDE for short, the black hole shoots out large amounts of radiation as it pulls in stellar material, resulting in massive flashes.
This event, detected by MIT researchers, shows a TDE much closer than anything we’ve seen so far. The event, called WTP14adbjsh, takes place in the galaxy NGC 7392, 137 million light-years away, and allows us to see the startling glow produced when a black hole swallows a star.
It also represents a first by being caught in an unusual light. WTP14adbjsh was observed as a rather bright infrared flare rather than optical or X-ray. This suggests that there may be tidal disruption events that we missed because we weren’t looking in the right place.
“Finding this near TDE statistically suggests that there may be many such events that conventional methods have not seen,” says MIT astrophysicist Christos Panagiotou.
