A radio telescope in New Mexico picked up signs of a black hole in June of 2021. It hadn't eaten in a long time.
Six telescopes were used to observe the ejection event, four of which were located in North America, South America, Africa and Australia. Three years ago, a star was eaten by a black hole. The team's research is in a journal.
The lead author of the study, a research associate at the Center for Astrophysics, said that the study caught them completely by surprise.
There is a radio-bright event taking place. When a star passes too close to a black hole it is called a tidal disruption event. The black hole's accretion disk has spaghettified star material that circles it instead of being sucked into it. Astronomers can see signals from Earth. The stars are torn apart as they travel through the black holes.
It is not uncommon for black holes to throw stellar material back into space. Three years is an uncommon amount of time for a black hole to have lunch. When a star is spaghettified by a black hole the regurgitations are quick.
