Samsung universe Department staged a "tug-of-war game"

These three scuffle galaxies 100 million light-years away from us far

Hubble captured the three galaxies of traction due to the gravitational tug-of-war competition and staged photographs, which can lead to large galaxies merge, one of a galaxy is likely to be swallowed. World War II happened in this galaxy at 100 million light-years from our distant constellation in the Southern Fish, which also eventually the outcome of a very long time until required. In this photograph, the location of the center-left is NGC7173, the lower right corner are NCG7176, these two galaxies seem to be relatively calm, while the middle-right position of NGC7174 its neighboring peers about pulling its spiral arm has led to a deformation.

World War II photographs of the galaxies are from the Hubble Space Telescope's Advanced Camera for Surveys filming, allowing astronomers to see galaxies interstellar gas flows from one galaxy to another, thus revealing the complex interactions between galaxies. Galaxies in this battle, unfortunately the previous galaxy NGC7174 may seem more like our Milky Way, the same with a spiral shape, but now it seems a totally different. NASA scientists think NGC7174 galaxy will be swallowed its oval-shaped neighbor, which broke out a new wave of star birth. This two elliptical galaxies will eventually merge, forming a single super-galaxy, its size is estimated good times than our Milky Way galaxy.

The three fights are from our galaxy 100 million light-years distant clusters of galaxies HCG90 members, HCG90 clusters of galaxies have 16 galaxies are close constellation, one of many galaxies are dwarf galaxies. Clusters of galaxies is HCG90 Canadian astronomer Paul Hickson (Paul Hickson), named after him in the 20th century during the first 80 of these small clusters to classify.
