Scientists have identified a black hole that erupts matter three years after destroying a star, and this type of phenomenon can usually be seen during the event, and Harvard researchers are still unsure why the delay occurred. , as they observed the black hole for several months after devouring the young star in 2018, but by chance they decided to reconsider it in 2021.
According to the British newspaper “Daily Mail”, it was then that they discovered the radio waves emitting it violently, as if it were “ejecting a bunch of material from the star that ate it years ago.”
“It completely surprised us,” said Yvette Sindez, an associate researcher at the Center for Astrophysics and lead author of the event study. “No one has ever seen anything like it before.”
When a star gets very close to a black hole, it undergoes a “stretching” process, where it is vertically stretched and compressed horizontally by a strong gravitational field.
These are known as tidal disturbance events, or TDEs, and are known to emit light when they occur, because the elongated material orbits the black hole and heats up, creating a flash that astronomers can detect millions of light-years away. distance. the black hole cannot successfully consume it by occasionally being pushed into space.
