"James Webb's Mind-Blowing Discovery: Ancient Quasars Illuminate Cosmic Web and Galaxies"
The James Webb Space Telescope has made a groundbreaking discovery by capturing starlight from ancient quasars, allowing astronomers to observe galaxies that existed when the universe was less than one billion years old. The observed galaxies have masses between 30 billion and 130 billion times that of the sun, with black holes weighing 200 million to 1.4 billion solar masses. This finding provides valuable insights into the early universe and supports the theory that quasars are formed through galactic mergers that fuel supermassive black holes.
