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 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. [53] 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). [ 54 ]
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 .
Andromeda Galaxy: Andromeda: Andromeda, which is shortened from "Andromeda Galaxy", gets its name from the area of the sky in which it appears, the constellation of Andromeda. [citation needed] Andromeda is the closest big galaxy to the Milky Way and is expected to collide
The Andromeda Galaxy with M110 at upper left and M32 to the right of the core 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.
A magnificent cloud of diffuse halo of plasma surrounding our galactic neighbor, Andromeda, was recently mapped by astronomers using the Hubble Space Telescope. This close proximity means that ...
NGC 891 (also known as Caldwell 23, the Silver Sliver Galaxy, and the Outer Limits Galaxy) is an edge-on unbarred spiral galaxy about 30 million light-years away in the constellation Andromeda. It was discovered by William Herschel on October 6, 1784. [3] The galaxy is a member of the NGC 1023 group of galaxies in the Local Supercluster.
Andromeda I is part of the local group of galaxies and a satellite galaxy of the Andromeda Galaxy (M31). It is roughly 3.5 degrees south and slightly east of M31. [ 6 ] As of 2005, it is the closest known dSph companion to M31 [ 7 ] at an estimated projected distance of ~40 [ 4 ] kpc or ~150,000 [ 6 ] light-years.
