Scientists have confirmed the theory that black holes have a negative impact on the evolution of their host galaxies.
Authors of a new study published in the journal Nature and using the Webb Space Telescope have been able to confirm for the first time the theory that active black holes rapidly stop new star formation in massive galaxies as energy and matter are ejected from space. Phys writes the disks around them.

Some large galaxies have active nuclei; This means that at their centres, there are supermassive black holes that consume the surrounding matter very quickly. Some of this matter flies back into space with radiation from the accretion disks surrounding black holes. It was assumed that the most active black holes, with the help of their emissions, can quickly remove from the galaxy the gas necessary for the formation of new stars. Thus, galaxies where star formation stops die.
New observations of a galaxy 10 billion light-years away have provided the first direct confirmation that large amounts of gas are being removed from the galaxy by the activity of a black hole.
Galaxies where new stars form continue to change and evolve, but dead galaxies become stagnant and their evolution stops. Although astronomers still don’t know much about how galaxies evolve, a new study provides direct evidence that a black hole is involved in the galaxy’s evolution process.
According to scientists, black hole emissions trigger a rapid outflow of gas necessary for the formation of new stars, and this process occurs faster than molecular gas clouds collapse into new stars.
Scientists have discovered that more than 90% of the galactic wind consists of neutral gas, which is why it was almost never seen in past studies. Until now, astronomers had only observed hot ionized gas, but the Webb telescope made it possible to see cold neutral gas as well.
As I already wrote FocusMirrors in space will help increase clean energy production on Earth. An American company is preparing to launch a prototype of an orbital mirror that will reflect sunlight to solar power plants even in the dark.
Moreover Focus He wrote that scientists were able to reconstruct the process by which radiation bursts occurred around the black hole at the center of the Milky Way.
We would like to remind you that the SLIM lander, which landed on the Moon in January and was expected to operate there for a short time, is still alive and continues to be sent to Earth to this day. The Japanese module once again surprised scientists by managing to survive the third cold night of the month, as written before Focus.
