Astronomers first discovered that black holes can help the formation of new stars. Such a connection was revealed by specialists, watching the black hole in the dwarf Galaxy Henize 2-10. An article with the results of the study was published in the Nature magazine.
Henize 2-10 is a dwarf galaxy located at a distance of 34 million light years, which occurs outbreaks of star formation. The data obtained by the Hubble Space Telescope show that from a black hole there is an outflow of hot gas, which extends towards the areas of birth of new stars located in 230 light years. This thread crashed into a dense dust cloud and gas a few million years ago, and the clusters of young stars are now lined up perpendicular to the direction of emissions from the black hole. The flow rate is more than one million kilometers per hour.
Scientists note that this effect is opposite to what is observed in large galaxies, where the material falling on the black hole is carried out in the form of jets at a speed close to the speed of light. Gas clouds that will fall on the path of such a relativistic string will be heated too much in order to form stars. However, in the case of a dwarf galaxy, the outflow from the black hole was soft enough and squeezed the gas in the clouds to the degree optimal for star formation.
