Large galaxies absorb small
|Automatic translation||Updated June 01, 2013|
Large galaxies grow by attracting small galaxies as they pass nearby. The Milky Way, our own galaxy practice this kind of galactic cannibalism, absorbing smaller galaxies captured by the gravitational force of the Milky Way. In fact, this practice is common throughout the universe. The images below illustrate the practice against gravity. This beautiful pair of interacting galaxies is in the constellation Eridanus (the river). It is located at more than 50 million light-years away and spans 100,000 light years.
