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 ...
NGC 708 is an elliptical galaxy located 240 million light-years away [2] in the constellation Andromeda and was discovered by astronomer William Herschel on September 21, 1786. [3] It is classified as a cD galaxy [ 4 ] [ 5 ] and is the brightest member of Abell 262 .
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 ...
NASA recently released images of the Andromeda galaxy, an empire of stars, that is the Milky Way galaxy's closest neighbor. This photo shows the Milky Way as seen from Black Balsam, mountain range ...
However the galaxy, although appearing centrally in the group in the sky, has a radial velocity higher than that of the other members of the group, indicating it is lying in the background. [7] Makarov and Karachentsev consider the galaxy a member of the IC 239 group, along with NGC 1023C, and is located in the same galaxy cloud with NGC 1023 ...
NGC 523, also known as Arp 158, from the ARP catalog is a spiral galaxy located in the constellation Andromeda. [1] It was discovered separately by William Herschel on 13 September 1784, and by Heinrich d'Arrest on 13 August 1862. d'Arrest's discovery was listed as NGC 523, while Herschel's was listed as NGC 537; the two are one and the same.

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] M31 is one of the most distant objects visible to the naked eye, 2.2 million light-years from Earth (estimates range up to 2.5 million light-years). [ 55 ]
NGC 477 is a spiral galaxy in the constellation Andromeda. [1] It is located approximately 250 million light-years from Earth and was discovered on October 18, 1786 by astronomer William Herschel. [2] [3] One supernova has been observed in NGC 477: SN 2002jy (type Ia, mag. 16.3). [4]
