[디지털투데이 AI리포터] A black hole with more than 30 billion solar masses has been discovered.
According to the Gigajin IT media on the 30th (local time), a research team at Durham University in the UK has discovered a supermassive black hole that is over 30 billion times the mass of the sun. This black hole is located in the Abell galaxy cluster, 2.7 billion light years from Earth.
The center of a black hole is under a gravitational pressure from which even light cannot escape. Most black holes are in an active state that releases energy, but inactive black holes are less radiant and difficult to observe. One way to detect these invisible black holes is to use gravitational lensing.
If a massive object such as a black hole is in the field of observation, space and time around it are distorted, and the light bends and stretches as if passing through a lens . Through this refraction, the existence of a black hole can be confirmed.
Based on the characteristics of these gravitational lenses, the research team confirmed that a supermassive black hole with a mass of more than 30 billion times the mass of the sun exists at the center of Abel.
Said Dr. Durham University’s Nightingale, “By checking the gravitational lensing effect, we can study inactive black holes. This method allows us to detect more black holes and uncover the history of the universe.”
