"Ancient Quasar Halts Galaxy's Star Formation at Dawn of Time, Astronomers Discover"

Astronomers have observed an ancient supermassive black hole quenching a galaxy's star formation just 900 million years after the Big Bang, confirming theoretical predictions. The black hole, known as a quasar, ejects high-speed torrents of gas, preventing the formation of stars by disrupting the flow of molecular gas, which is essential for star formation. This discovery sheds light on the role of quasars in shaping the early universe and will guide future research into understanding how these phenomena influenced the formation of the first galaxies.
