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
Zooming In on the Andromeda Galaxy, also known as Gigapixels of Andromeda, is a 2015 composite photograph of the Andromeda Galaxy produced by the Hubble Space Telescope. It is 1.5 billion pixels in size, and is the largest image ever taken by the telescope. [1] At the time of its release to the public, the image was one of the largest ever ...
NGC 7662 is a planetary nebula located in the northern constellation Andromeda.It is known as the Blue Snowball Nebula, Snowball Nebula, and Caldwell 22.This nebula was discovered October 6, 1784 by the German-born English astronomer William Herschel.
Andromeda's borders contain many visible distant galaxies. [11] The most famous deep-sky object in Andromeda is the spiral galaxy cataloged as Messier 31 (M31) or NGC 224 but known colloquially as the Andromeda Galaxy for the constellation. [54]

Messier 32 (also known as M32 and NGC 221) is a dwarf "early-type" galaxy about 2,490,000 light-years (760,000 pc) from the Solar System, appearing in the constellation Andromeda. M32 is a satellite galaxy of the Andromeda Galaxy (M31) and was discovered by Guillaume Le Gentil in 1749.
Messier 110, or M110, also known as NGC 205, is a dwarf elliptical galaxy that is a satellite of the Andromeda Galaxy in the Local Group. [ 9 ] Early observational history
1912 – Vesto Slipher's spectrographic studies of spiral nebulae find high Doppler shifts indicating recessional velocity. 1917 – Heber Curtis finds novae in Andromeda Nebula M31 were ten magnitudes fainter than normal, giving a distance estimate of 150,000 parsecs supporting the "island universes" or independent galaxies hypothesis for spiral nebulae.
