Astronomers have recently identified the most distant dormant black hole known to date, located in the galaxy MRG-M0138, approximately 10 billion light-years from Earth. This significant finding was made possible through data from NASA’s James Webb Space Telescope. The black hole is characterized as dormant because it does not accrete surrounding matter and has not been associated with any quasar activity. To locate this nearly invisible black hole, researchers employed gravitational lensing, a phenomenon where the light from distant objects is bent by the gravity of an intervening galaxy. By analyzing the movement of stars near the black hole, they estimated its mass to be around 6 billion times that of the Sun. This discovery not only sheds light on the characteristics of dormant black holes but also opens avenues for further research into their behavior and evolution, which are still largely unknown. Moreover, astronomers hope that this breakthrough will facilitate the detection of other similar black holes, helping to address many unanswered questions in astrophysics.
