Universe’s oldest X-ray-spitting quasar could reveal how the biggest black holes were born

Astronomers using NASA’s James Webb Space Telescope (JWST) and Chandra X-ray Observatory have discovered the oldest and most distant X-ray-spitting quasar in the known universe, and it seems to be powered by the “seed” of an ancient supermassive black hole.

Quasars are the bright hearts of active galaxies, which are fueled by active supermassive black holes that cause infalling matter to emit intense thermal radiation as they feed. Quasars can be so bright across the entire electromagnetic spectrum that they often outshine the combined light from every star in the galaxy surrounding them.
