Description:

This is an image of a portion of M31, the Andromeda galaxy, that I posted a few years ago showing its giant star cluster NGC 206, which contains blue supergiant stars and spans over 4000 light-years. In this version, I have also labeled 18 of M31's globular clusters visible in the image.
