(DESCRIPTION) 
 White and yellow stars and dust clouds trail from two galaxies. 

Text, HUBBLE SPACE TELESCOPE. THE MICE (NGC 4676). Stars and gas stream like tails away from a pair of galaxies nicknamed The Mice. Such starry streamers are a tell-tale sign that a galaxy collision is in full swing. 

As two galaxies sweep around each other, their gravitational attraction pulls strongest at the nearest stars and gas. 

The gas and stars farthest from the heart of the action trail behind as the galaxies perform their gravitational dance.
