Like the Milky Way, the Andromeda Galaxy has smaller satellite galaxies, consisting of over 20 known dwarf galaxies. The Andromeda Galaxy's dwarf galaxy population is very similar to the Milky Way's, but the galaxies are much more numerous. [127] The best-known and most readily observed satellite galaxies are M32 and M110. Based on current ...
NASA recently released images of the Andromeda galaxy, an "enticing empire of stars" that can be seen with the naked eye if weather conditions are just right. About 100 years after astronomer ...
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]
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 ...

Naked-eye galaxies Galaxy Apparent Magnitude Distance Constellation Notes Milky Way: −6.5 [a] 0 Sagittarius (centre) This is the galaxy containing the Sun and its Solar System, and therefore Earth. Most things visible to the naked eye in the sky are part of it, including the Milky Way composing the Zone of Avoidance. [12] Large Magellanic ...
NASA has shared some mesmerizing space pictures taken this year. Here are the highlights.
A ring galaxy has a ring-like structure of stars and interstellar medium surrounding a bare core. A ring galaxy is thought to occur when a smaller galaxy passes through the core of a spiral galaxy. [97] Such an event may have affected the Andromeda Galaxy, as it displays a multi-ring-like structure when viewed in infrared radiation. [98]
