The New Looks of Universal Galactic Collisions
“The consequence was that the merged black hole, the final product, the new black hole was expelled from the galaxy,” Komossa said.
Galactic collisions are taking on a whole new look, with the latest Hubble Space Images showing them in action, taking on a variety of peculiar forms. Much more common than thought, it has been found that they are more common in the early days of the developing universe than that of today. This closeness brought about a lot more collisions than that of today. And recently, what has been seen is a colossal black hole exiting its home galaxy, after a huge cosmic merger just took place viewed by the Hubble.
Released on April 18th, a series of 59 Hubble photographs are said to be the largest collection ever released as one set, proving that the most isolated galaxies are capable of showing signs of mergers within their internal structure. These mergers occur at a pace of hundreds of millions of years for completion, rushing toward each other at a high pace—hundreds of kilometers per hour.
The Milky Way of today is living proof with the pieces of remaining smaller galaxies within close proximity of it, devouring everything within its path. Still actively consuming, presently it is working on the Sagittarius dwarf elliptical galaxy—an area with its diameter about 10,000 light years, and 70,000 light years away from Earth while moving in a polar orbit, at a distance of 50,000 light years from the core of the Milky Way. Beside it with devour rights occurring in about two billion years is the Andromeda galaxy, projected to devour the Milky Way with the resulting future elliptical galaxy dubbed
“Milkomeda”.
A resulting new theory from the recent Hubble images is showing that when two galaxies collide, the core black holes may possible fuse together. With no proof to back this theory, this new theory states that energy may be released which will propel the resulting new black hole onward to space, released from its parent galaxy. What has been found instead of the actual event itself is the result of the merger—a 100-million-solar mass black hole that is getting ready to leave its parent galaxy.
