The Andromeda Galaxy is one of my favorites and never seems to disappoint. Also known as Messier 31, this galaxy is often compared to our own Milky Way since it has a mass of the same order of magnitude (1 trillion solar masses). However, it has an estimated 1 trillion stars which is about double of our home galaxy. The light in the photo began it's journey to Earth about 2.5 million years ago when we were just beginning the ice ages which would last until about 11,700 years ago.
