Supermassive black holes are located in the centers of most of the studied galaxies. Astronomers have long believed that they play a very important role in the processes of star formation. As you know, not all matter that falls in the vicinity of a black hole is absorbed by it. Some are thrown out in the form of jets and plasma streams, which can be somewhat compared to winds. It is believed that such winds can "blow" interstellar gas out of the galaxy, thereby slowing down, if not completely stopping the star formation processes in it. But as recent data show, these processes are much more complex than previously thought. Black holes can not only destroy but also create.
Using the Very Large Telescope at Paranal Observatory, a group of European astronomers observed a pair of colliding galaxies known as IRAS F23128-5919. They are located 600 million light-years from the Milky Way. Scientists were able to see colossal eruptions of matter from the vicinity of a supermassive black hole located in the core of one of the galaxies. Within these ejections, radiation was found that is characteristic of newborn stars, whose age is less than several tens of millions of years. Preliminary analysis shows that they are hotter and brighter than the stars that form in the galactic disks. According to astronomers, this means that young stars formed directly from material ejected by black holes.
Astronomers were also able to record the movement of these young luminaries. Most of them are moving away at very high speeds from the center of the galaxy. This confirms that they are located in the ejected material stream. Such stars can pick up enough speed to leave their home galaxy forever.
