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.
Size (left) and distance (right) of a few well-known galaxies put to scale. There are an estimated 100 billion galaxies in all of the observable universe. [1] On the order of 100,000 galaxies make up the Local Supercluster, and about 51 galaxies are in the Local Group (see list of nearest galaxies for a complete list).
Southern Pinwheel Galaxy, ESO 444- G 081, IRAS 13341-2936, NGC 5236, UGCA 366, MCG-05-32-050, PGC 48082 [6] Messier 83 or M83 , also known as the Southern Pinwheel Galaxy and NGC 5236 , is a barred spiral galaxy [ 7 ] approximately 15 million light-years away in the constellation borders of Hydra and Centaurus .
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 ]
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 ...
The Hubble telescope captures the brightest galaxies ever seen, thousands of galaxies act like lenses that magnify light, making them appear super bright.
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).
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.
