The Andromeda Galaxy is a barred spiral galaxy and is the nearest major galaxy to the Milky Way. It was originally named the Andromeda Nebula and is cataloged as Messier 31 , M31 , and NGC 224 . Andromeda has a D 25 isophotal diameter of about 46.56 kiloparsecs (152,000 light-years ) [8] and is approximately 765 kpc (2.5 million light-years ...

The Andromeda Galaxy (M31) has satellite galaxies just like the Milky Way. Orbiting M31 are at least 13 dwarf galaxies: the brightest and largest is M110, which can be seen with a basic telescope. The second-brightest and closest one to M31 is M32. The other galaxies are fainter, and were mostly discovered starting from the 1970s.
Description Andromeda galaxy Ssc2005-20a1.jpg. English: NASA's Spitzer Space Telescope has captured stunning infrared views of the famous Andromeda galaxy to reveal insights that were only hinted at in visible light. This Spitzer's 24-micron mosaic is the sharpest image ever taken of the dust in another spiral galaxy.
Original - Andromeda Galaxy in infrared, by the Spitzer space telescope. The Andromeda Galaxy is a spiral galaxy 2.5 million light-years away in the constellation Andromeda, making it the nearest spiral galaxy to the Milky Way. The exposure time of this image was 100 sec/pixel, and its scale is 2.8 x 0.8 degrees.
1995 — First detection of small-scale structure in the cosmic microwave background. 1995 — Hubble Deep Field survey of galaxies in field 144 arc seconds across. 1998 — The 2dF Galaxy Redshift Survey maps the large-scale structure in a section of the Universe close to the Milky Way. 1998 — The Hubble Deep Field South is compiled.
English: The Andromeda Galaxy is a spiral galaxy approximately 2.5 million light-years away in the constellation Andromeda. The image also shows Messier Objects 32 and 110, as well as NGC 206 (a bright star cloud in the Andromeda Galaxy) and the star Nu Andromedae. This image was taken using a hydrogen-alpha filter.
