Scientists have been able to find a galaxy in which star formation has stopped. The James Webb Space Telescope helped with this.
What is known
GS-9209 is the most ancient of all known extinct galaxies. Almost all of its stars appeared between 600 million and 800 million years after the Big Bang. But then the formation of stars suddenly stopped.
For 200 million GS-9209 was able to gain a mass of 40 billion Suns, which corresponds to the mass of the Milky Way. Scientists believe that the abrupt cessation of star formation may be due to the behavior of a supermassive black hole, which is located at the center of the discovered galaxy.
According to astronomers from the Royal Observatory in Edinburgh, the black hole, in the process of absorbing matter, turned into a quasar, the radiation of which is 1 trillion times greater than the radiation of stars. This is enough for the gas needed to form stars to stop compressing.
Now the researchers plan to study the galaxy GS-9209 in more detail. The Extremely Large Telescope of the European Southern Observatory will help them with this. But the observatory is under construction.
