3D model of the stellar stream in the Umbrella galaxy- NGC 4651

This is an animated three-dimensional rotating computer model of the Umbrella galaxy (NGC 4651).

The disk of the main galaxy is indicated by the concentric blue circles. The path of the dwarf satellite galaxy through space is traced by the curved green line. The white dots represent stars that once belonged to the former satellite galaxy but were ripped off by tidal forces into a long stream of stars.
