The Andromeda Galaxy, Messier 31 or M31, is the nearest spiral galaxy to our Milky Way galaxy.The Andromeda Galaxy is the largest galaxy of the Local Group, which also contains the Milky Way, the Triangulum Galaxy, and about 30 other smaller galaxies. The Andromeda galaxy is the most studied galaxy outside our own. The structure of Andromeda is so similar to that of the Milky Way as in it contains generally the same celestial features, such as a spiral structure, globular and open clusters, interstellar dust and gas, planetary nebulae, supernova remnants, and companion galaxies.
While the two galaxies are far apart, they are moving towards each other at the rate of about 100 to 140 kilometers per second, the equivalent of 400 light years every million years. Thus a potential collision may be coming up in about 3-5 billion years between the two galaxies.Equipment location:Banat area, VRANIUTZ - Romania.
