Hubble discovers black hole spurring star formation in dwarf galaxy

(ORDO NEWS) — Black holes are often described as “cosmic monsters” – tearing stars apart, “devouring” everything that comes close to them, and not even letting light out of their tenacious embrace. However, new evidence from NASA/ESA’s Hubble Space Telescope puts the black hole in a different light, as an object that initiates star formation rather than suppressing it.

New images and spectroscopic observations of a starburst dwarf galaxy called Henize 2-10 clearly show an outflow of gas from the black hole to a bright region of active star formation, like an umbilical cord, which further stimulates the formation of new star clusters in this already dense region of space. space. Astronomers have previously assumed that a dwarf galaxy may contain a black hole, similar to the supermassive black holes that lie in larger galaxies.

A more detailed study of dwarf galaxies, whose sizes almost do not increase with time, can shed light on the problem of the formation of the first embryos of supermassive black holes and their evolution throughout the history of the Universe.

The dwarf galaxy Henize 2-10 lies about 30 million light-years away, towards the constellation Compass of the southern sky. In this galaxy, astronomers led by Amy Reines discovered a black hole with a mass of about 1 million solar masses in 2011 and wondered about the possible role of such a black hole as a seed in the formation of larger supermassive black holes. At present, astronomers have no consensus on the mechanism by which supermassive black holes form from stellar-mass black holes.
