The James Webb Space Telescope (JWST) has detected the most distant dormant black hole in the universe, situated in the galaxy MRG-M0138, over 10 billion light-years from Earth. This discovery, detailed in a study published in *Science*, reveals that the black hole has a mass approximately six billion times that of the sun. Researchers believe that MRG-M0138 once hosted a quasar that rapidly consumed gas, halting star formation in the galaxy. The black hole is invisible in all light wavelengths, making its detection challenging; however, scientists employed gravitational lensing from a foreground galaxy to magnify the image of MRG-M0138, allowing them to analyze star motions around the black hole. This technique opens avenues for understanding black hole development and their influence on galaxy evolution. The research team, led by Andrew Newman from Carnegie Science, is also investigating other early-universe galaxies to further explore the dynamics of star formation cessation. Future observations with the Euclid and Nancy Grace Roman Space Telescopes are anticipated to enhance the search for similar ancient galaxies.
