It consists of two clusters of galaxies in a "dumbbell" shape: the Milky Way and its satellites form one lobe, and the Andromeda Galaxy and its satellites constitute the other. The Triangulum galaxy (left) is a spiral galaxy and the third largest galaxy in the local group, it contains 50 billion stars. NGC 147 (top centre) is a dwarf elliptical galaxy and IC 10 (top right) is a dwarf irregular galaxy, they both contain tens of millions of stars. The Local Group of galaxies includes the Milky Way, M31 (the Andromeda galaxy), and many dwarf galaxies. The beautiful 3D map of space that plots our nearest galaxies - and reminds us how tiny Earth is. Researchers mapped the motions of nearly 1,400 nearby galaxies in the Local Supercluster over the course of the last 13.5 billion years. Shown below are four of the galaxies in the Local Group.
