M31, the Andromeda Galaxy, with M32 and M110 (Sept. 19, 2012)



Behold the great Andromeda Galaxy!  In this image, you also see galaxies M32 (the small one, upper left) and M110 (the larger one, lower right).  M32 and M110 are satellite galaxies of M31.  Also visible at lower left is a large group of young stars in the spiral arm or ring of the large galaxy.  That group and the outer areas of the galaxy are bluer because the stars in them are younger and hotter than the stars in the galaxy's central bulge.
