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.
BX442 (Q2343-BX442 [1]) is a grand design spiral galaxy of type Sc. [1] It has a companion dwarf galaxy.It is the most distant known grand design spiral galaxy in the universe, with a redshift of z=2.1765 ± 0.0001. [1]
Up until the discovery of JADES-GS-z13-0 in 2022 by the James Webb Space Telescope, GN-z11 was the oldest and most distant known galaxy yet identified in the observable universe, [7] having a spectroscopic redshift of z = 10.957, which corresponds to a proper distance of approximately 32 billion light-years (9.8 billion parsecs).
Galaxies 1997 − 1998 z = 4.92 These were the most remote objects discovered at the time. The pair of galaxies were found lensed by galaxy cluster CL1358+62 (z = 0.33). This was the first time since 1964 that something other than a quasar held the record for being the most distant object in the universe. [136] [139] [140] [137] [134] [141] PC ...
The James Webb Space Telescope just looked back in time a whopping 13.4 billion years. You read that right.And doing so allowed scientists to find the earliest galaxies humanity has ever seen (so ...
As one of the brightest galaxies in the sky, the Sculptor Galaxy can be seen through binoculars and is near the star Beta Ceti. It is considered one of the most easily viewed galaxies in the sky after the Andromeda Galaxy. [5] [8] The Sculptor Galaxy is a good target for observation with a telescope with a 300 mm diameter or larger. [8]
The James Webb Space Telescope keeps finding galaxies that shouldn’t exist, a scientist has warned. Six of the earliest and most massive galaxies that Nasa’s breakthrough telescope has seen so ...
M87 is one of the most massive galaxies in the local Universe. Its diameter is estimated at 132,000 light-years, which is approximately 51% larger than that of the Milky Way. [ 5 ] [ 6 ] As an elliptical galaxy, the galaxy is a spheroid rather than a flattened disc, accounting for the substantially larger mass of M87.
