Constellation: Andromeda
Distance: 2.5 Million Light Years
The Andromeda Galaxy is a member of the Local Group of galaxies which includes the Milky Way, and is the closest of all galaxies to our own. At a distance of 2.5 million light years, it is the most distant object visible to the naked eye (I am able to see it from my imaging site, especially with averted vision). A spiral galaxy similar in structure to the Milky Way, it is estimated to contain about 1 trillion stars, about twice as many as our galaxy. Unlike most galaxies, the Andromeda Galaxy and the Milky Way are moving toward each other, and a close encounter or collision is expected in about 4.5 billion years.
Two satellite galaxies of M31 are visible in the image: M32, a dwarf elliptical galaxy that projects over the upper left part of M31, and the larger M110, seen below M31.
