Andromeda Galaxy
M31 / NGC 224
The Andromeda Galaxy is the closest neighboring galaxy, a mere 2.5 million light-years away. It is the only galaxy visible to the naked eye - but just barely. The galaxy is made up of around 1 trillion stars.
This is our best picture of the Andromeda Galaxy so far. Weather was nice and we were able to use 45 of the 48 frames we shot. In the picture there are also two satellite (“dwarf”) galaxies of Andromeda. To the left is M32 (NGC 221) and to the bottom right is M110 (NGC 205). There are even some extragalactic nebulae visible (brighter red/blue regions).
