Astronomers recently discovered 11 galaxies which got interrupted by unpleasant gravitational turbulence and got kicked away from their home clusters. Now these galaxies are marooned in an unknown inter cluster space, facing a lonely future ahead.
Igor Chilingarian, who is an astronomer at the Harvard Smithsonian Center for Astrophysics and Moscow State University explained this phenomenon. He said that it occurs when a galaxy is traveling at a higher speed than the galaxy's escape velocity, according to Discovery News.
The astronomer further explained that this phenomenon is similar to that of a rocket launch, in which the rocket is supplied with enough velocity for the object to exceed its escape velocity and escape from the surface of Earth.
The 11 galaxies which "escaped" from their home clusters are known to be extremely rare and tiny. Despite being flung away, they are still moving at a very high speed, according to News World Map.
The researchers say that one more explanation could be that these tiny galaxies were also present in a gravitational mechanism similar to our galaxy. Milky Way can interrupt the orbits and produce runaway stars.
In addition to all these theories, astronomers proposed one more theory called the Classic three body interaction. In this phenomenon, one of the stars of a binary star cluster acquires a higher velocity and becomes a hypervelocity star when the pair comes close to a black hole.
In such a scenario, the black hole swallows one of the stars while the other star is flung away with a force.
