Description

This object is the beautiful and massive Andromeda Galaxy, located only 2.5 million light years from earth in the constellation of its own name. It is the closest spiral galaxy to us and the farthest object that we can see with our naked eye.

Its apparent size is about 6 times the width of our full moon. The disk contains many billions of suns. The massive black hole at the center of the galaxy is not visible. NGC206, the brightest star cloud in the galaxy, is visible at lower right. Two satellite galaxies are in the same view - M110 to the upper right and M32 to the lower left.

Over 500 globular clusters have been identified as belonging to M31.  I have identified the top 10 brightest globular clusters in the mouseover.  

Many dark dust lanes are evident from near the core all the way out to the outer ring. It is interesting to me how the dust lanes on the near (right) side of the galaxy disk show up much more prominently than the dust lanes on the far (left) side.

My favorite aspect of this image is the many star clusters and Ha regions faintly visible in the outer half of the galaxy disk, especially top left and lower right.
