Description

The Andromeda Galaxy. (M31) (M110) (M32) (ngc206) Located in the Constellation Andromeda. The Galaxy type is a spiral galaxy approximately 2.5 million light-years from Earth and headed this way. Its the nearest galaxy to us the Milky Way galaxy. The Andromeda Galaxy has a diameter around 220,000 light years and around 10 billion years old. The number of stars contained in the Andromeda Galaxy is estimated at one trillion roughly twice the number estimated for our Milky Way galaxy. The Andromeda Galaxy is among the brightest of the Messier objects making it visible to the naked eye from Earth on a dark moonless night. Andromeda and the Milky Way are heading on a collision course that will alter the structure of the two galaxies forever. The galaxies are rushing closer to one another at about 70 miles per second. Astronomers estimate that Andromeda will collide with the Milky Way around 4 billion years, with the merger concluding 6 billion years from now. By that time, the sun will have swollen into a red giant and swallowed up the terrestrial planets. So the Earth is doom one way or the other either by our Milky Way colliding with the Andromeda galaxy or our Star the Sun dying out by running out of fuel.



NGC 221 (M32) (Top) is a dwarf "early-type" galaxy about 2,650,000 light-years (810,000 pc) s from our star system, appearing in the constellation Andromeda. M32 is a satellite galaxy of the Andromeda Galaxy (M31)



NGC 205 (M110) (lower) This dwarf elliptical galaxy is a satellite of the famous Andromeda galaxy (M31). Unlike most elliptical galaxies, NGC 205 shows evidence of recent star

formation. Charles Messierʼs records suggest that he observed this galaxy with M31 and M32, but did not list it in his catalogue of comet-like objects.



NGC 206 (right) a young bright blue star cluster. Its youngest massive stars are less than 10 million years old. Located in a spiral arm of the Andromeda Galaxy. Size around 4,000 light-years across.M32) (Top) is a dwarf "early-type" galaxy about 2,650,000 light-years (810,000 pc) s from our star system, appearing in the constellation Andromeda. M32 is a satellite galaxy of the Andromeda Galaxy (M31)
