Andromeda Galaxy core. Hubble Space Telescope image of the central region of the Andromeda Galaxy (M31, NGC 224). Two light sources, named P1 and P2, form a double nucleus at the core of the galaxy. At 2.2 million light years away, M31 is the closest major galaxy to our own Milky Way and is the largest member of our Local Group of galaxies. It is a spiral galaxy, although this image shows little of its extensive arms. Its full diameter is 150,000 light years.
