The James Webb Space Telescope (JWST) has detected what is believed to be the most distant quiescent black hole ever found. This supermassive black hole resides in MRG-M0138, a gravitationally lensed galaxy observed as it was when the universe was approximately 3 billion years old. The black hole's mass is estimated to be 6 billion times that of the Sun. The analysis of the data was performed using the NIRSpec Integral Field Spectrograph, an instrument aboard the JWST.
