The galaxy is located 30 million light-years away in the Pyxis constellation. While large galaxies are known to contain a supermassive black hole at their center, galaxies like Henize 2-10 have caused astronomers to debate if the same is possible in smaller-scale cosmic settings.
Compared to the massive Milky Way galaxy and its billions of stars, Henize 2-10 only has about a tenth of the stars.
“From the beginning I knew something unusual and special was happening in Henize 2-10, and now Hubble has provided a very clear picture of the connection between the black hole and a neighboring star forming region located 230 light-years from the black hole,” said study author Amy Reines, an assistant professor in the department of physics at Montana State University, 在一份声明中.

2011 study revealing the first evidence for a black hole in the galaxy
The outflow of gas from the black hole was moving about a million miles per hour when it slammed into the dense gas cloud and then spread out. New clusters of stars can be seen flourishing along its path.
It’s a rare case of a black hole helping stars to form, rather than tearing them apart. In large galaxies, black holes spew out superheated jets of material that nearly reach the speed of light. Any gas clouds unfortunate enough to be in the way of these jets would become so hot, they wouldn’t be able to cool down enough to form stars.
The smaller black hole inside of dwarf galaxy Henize 2-10 is releasing material at a much slower and gentler speed, creating just the right conditions for star birth.
Studying dwarf galaxies, or those that have remained small over time, could help astronomers discover how supermassive black holes came to exist early on in the history of the universe.
