NASA’s Transiting Exoplanet Survey Satellite (TESS) captured the rare scene of black holes tear apart stars, and the scale is quite astonishing. Scientists say that this kind of “cosmic event” usually only occurs once every 10,000 to 100,000 years. Observations It’s very difficult.

Black holes tear apart stars

It is understood that the phenomenon of black holes tearing stars apart is also called “tidal interference”. Simply put, “tidal interference” is the phenomenon when a star is absorbed when it is close to the black hole. It may be torn into a long “line” and Being sucked into a black hole. This “tidal disturbance” event is called “ASASSN-19bt”. The black hole that is one of the protagonists of the event is located in the 2MAX J0700137-6602251 galaxy in the Volans star cluster about 375 million light-years away from the Earth. Its mass is about 6 million of the sun. times.

Scientists say that this phenomenon is still in the early stages of “tidal interference”, which also leaves more time for humans to observe this phenomenon.

Humankind’s knowledge of black holes has always been very limited. The detection of the process of tearing apart stars this time will help scientists better understand the evolution of black holes in different periods and put forward more relevant theories or speculations.

It is worth mentioning that Patrick Varley, a co-author of this study and a National Science Foundation graduate researcher at Ohio State University, also said, “The global robotic telescope network ASAS-SN provided great help for this observation because it A network of robots disappeared very quickly, and we were able to detect data from this ‘tidal disturbance’.”
