Description: The Great Galaxy in Andromeda or M31 as it is also known is one of the furtherest objects that can be seen with the unaided human eye. It is about two and a half million light years away. More than a thousand years ago the a Persian astronomer named Al-Sufi described the Great Galaxy in Andromeda as a "small cloud" in his Book of Fixed Stars. Now there are few places on planet Earth like the Cosmic Campground where one can see it with the naked eye due to inappropriate night time lighting.
