The research could not only shake up astrophysical models of how galaxies evolve, but could also help scientists better understand how the mysterious substance dark matter-which accounts for the majority of a galaxy's mass content-is distributed throughout galactic structures. Black Hole in Our Neighboring Galaxy Could Help Uncover Hidden Population.
Massive, Colliding Black Holes May Expand Along With the Universe.Closest Supermassive Black Hole Pair To Earth On The Verge Of Collision."This begs the question, is this galaxy special or are other dwarf spheroidals likely to have supermassive black holes inside them?" And it lives inside a dwarf spheroidal galaxy, which are galaxies that shouldn't have supermassive black holes inside them. It's the second-closest known supermassive black hole, the first one being the one at the center of our galaxy. María José Bustamante, doctoral graduate from the University of Texas, Austin, and co-author of the study on the findings, said in a statement: "there is no explanation for this kind of black hole in dwarf spheroidal galaxies."īustamante told Newsweek: "There are several things that are remarkable about this discovery. The findings were published in The Astrophysical Journal. The black hole at the heart of the dwarf galaxy Leo I, a satellite galaxy of the Milky Way, is nearly as massive as the supermassive black hole at the heart of our galaxy.
Astronomers have discovered that a small satellite galaxy falling towards the Milky Way is home to an unusually massive black hole.
