Size (left) and distance (right) of a few well-known galaxies put to scale. The following is a list of notable galaxies.. There are about 51 galaxies in the Local Group (see list of nearest galaxies for a complete list), on the order of 100,000 in the Local Supercluster, and an estimated 100 billion in all of the observable universe.
As of 2024, NGC 5468 is the most distant galaxy in which Hubble Space Telescope has detected Cepheid variable stars, which are important milepost markers for measuring distances. [6] NGC 5468 forms a non-interacting pair with NGC 5472, which lies at a projected distance of 5.1 arcminutes. NGC 5468 belongs to the NGC 5493 galaxy group.
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 ...
SMACS J0723.3–7327, commonly referred to as SMACS 0723, is a galaxy cluster about 4 billion light years from Earth, [2] within the southern constellation of Volans (RA/Dec = 110.8375, −73.4391667).
In this zoomed-in detail of the Hubble image of Abell 370, the host galaxy where the 44 stars were discovered appears several times: in a normal image (left), and a distorted image appearing as a ...
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.

The galaxy and its companion, NGC 5195, [11] are easily observed by amateur astronomers, and the two galaxies may be seen with binoculars. [12] The Whirlpool Galaxy has been extensively observed by professional astronomers, who study it and its pair with NGC 5195 to understand galaxy structure (particularly structure associated with the spiral ...
In Hubble's galaxy classification scheme, M87 is an E0 galaxy. In 1922, the American astronomer Edwin Hubble categorized M87 as one of the brighter globular nebulae, as it lacked any spiral structure, but like spiral nebulae, appeared to belong to the family of non-galactic nebulae. [ 20 ]
