This is an acrylic painting
with a few digital additions. It shows the Andromeda Galaxy, M31, the
nearest large spiral system to our own Milky Way, which is comparable
in size. Looking over the shoulder of the great galaxy, we see one of
its small elliptical companion galaxies, then the Milky Way and the
Magellanic Clouds, about two and a half million light years away. In
the foreground is one of M31's many orbiting globular star clusters.
