Can Collision Of Evenly Matched Galaxies Create Something Interesting?


The violent collision between two galaxies is a common occurrence in the outer space. But this collision can sometimes create something really interesting by turning the black holes of the galaxies into two different quasars. Quasars are those celestial bodies that can emit an exceptionally massive amount of energy especially in the form of light and hence, they are one of the brightest objects in space.

The new research shows that the possibility of the formation of two quasars is higher if the collision takes place between two galaxies of roughly the same size. When one galaxy is exceptionally bigger than the other one, a single massive black hole is likely to be created with just one quasar which is obviously never as bright as two of them together. 

What Exactly Happens During The Collision?

The collision between two galaxies leads to merging of gas, dust, stars, and various other celestials bodies present in each one of them. Their black holes also merge into a supermassive black hole that stays
