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.
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 ...

[citation needed] First Seyfert galaxy: NGC 1068 (M77) Cetus: 1943 (1908) The characteristics of Seyfert galaxies were first observed in M77 in 1908; however, Seyferts were defined as a class ...
Most consider Roberts' magnum opus to be a photograph showing the structure of M31, the Great Nebula in Andromeda (now known as the Andromeda Galaxy). He made the photo on 29 December 1888, using his 20-inch (510 mm) aperture reflecting telescope made by Grubb. [ 11 ]

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
NGC 891 looks as the Milky Way would look like when viewed edge-on (some astronomers have even noted how similar to NGC 891 our galaxy looks as seen from the Southern Hemisphere [9]) and, in fact, both galaxies are considered very similar in terms of luminosity and size; [10] studies of the dynamics of its molecular hydrogen have also proven the likely presence of a central bar.
