BUT black hole removed material from star which he crushed three years ago, a find that has puzzled scientists.
“It took us by surprise, no one had ever seen anything like it before,” said Yvette Sendes, an astronomer at the Harvard-Smithsonian Center for Astrophysics who led the study. “As if it black hole he would suddenly start spewing a bunch of stuff from a star he ate years ago.”

In October 2018, it was noted that black hole, Located in a galaxy 665 million light-years from Earth, it tore apart a star that got too close.
This phenomenon is called tidal disruption (TDE) and is widespread among astronomers. They usually occur when objects such as stars approach black holes and the powerful gravitational force they encounter generates tidal forces that stretch the star in one direction and squeeze it in the other direction, “spageting” its body.
Because this material is in black hole, it heats up and generates a flash of light that astronomers can detect millions of light years away. Occasionally, black hole spits out some of this stellar material back into space.
However, this new TDE called AT2018hyz, black hole it ejects material at about 480 million kilometers per hour, about half the speed of light. The conditional number does not exceed 10% of the specified speed.
“This is the first time we’ve seen such a large delay between feeding and departure,” study co-author Edo Berger, a professor of astronomy at Harvard University, said in a statement.

Astronomers discovered this event while looking for signs of a TDE that has occurred in recent years. The data they collected in radio waves with the Very Large Array in New Mexico showed that this black hole mysteriously came back to life in June 2021.
The team studied the event in several wavelengths of light and with a variety of telescopes, including the VLA, the MeerKAT radio telescope in South Africa, and the Atacama Large Millimeter/submillimeter Array in Chile, and found that the most striking observations AT2018hyz They were on radio frequencies.
The team is now investigating whether the delay between feeding and emission is unique to AT2018hyz or if it’s a more common event that astronomers have missed.
