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.
NGC 4656/57 is a highly warped edge-on [3] barred spiral galaxy located in the local universe 30 million light years away from Earth in the constellation Canes Venatici. [4] This galaxy is sometimes called the Hockey Stick Galaxy or the Crowbar Galaxy. Its unusual shape is thought to be due to an interaction between NGC 4656, NGC 4631, and NGC ...
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).
The Milky Way [c] is the galaxy that includes the Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye.
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.
Six star systems have been found to have exoplanets. The Fornax Dwarf galaxy is a small faint satellite galaxy of the Milky Way. NGC 1316 is a relatively close radio galaxy. The Hubble's Ultra-Deep Field is located within the Fornax constellation. [1] It is the 41st largest constellation in the night-sky, occupying an area of 398 square degrees.
Messier 81 (also known as NGC 3031 or Bode's Galaxy) is a grand design spiral galaxy about 12 million light-years away in the constellation Ursa Major. It has a D 25 isophotal diameter of 29.44 kiloparsecs (96,000 light-years ).
NGC 6946, sometimes referred to as the Fireworks Galaxy, is a face-on intermediate spiral galaxy with a small bright nucleus, whose location in the sky straddles the boundary between the northern constellations of Cepheus and Cygnus.
