A Hubble Space Telescope image of the supergiant elliptical galaxy ESO 306-17. Supergiant elliptical galaxies are some of the largest galaxies known. The Condor Galaxy is a colossal spiral galaxy disturbed by the smaller IC 4970 .
Consists of at least 15 clusters plus other interconnected filaments. It is the most massive galaxy supercluster discovered so far. [19] Big Ring (2024) 1,300,000,000 Made up of galaxy clusters. (Theoretical limit) 1,200,000,000 Structures larger than this size are incompatible with the cosmological principle according to all estimates. However ...
A 2017 paper suggests that IC 1101 has the largest core size of any galaxy with a core radius of around 4.2 ± 0.1 kpc (13.70 ± 0.33 thousand ly) by fitting a model to a Hubble Space Telescope (HST) image of the galaxy. This makes its core larger than the one observed in A2261-BCG, which is 3.2 kpc (10 thousand ly).
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.
International Space Station: 450,000 kg (992,080 lb) Space station Listed mass includes attached vehicles and is estimated by ESA. [3] Completed station mass is 419,725kg [4] [5] LEO: In service: 1998– (at present size: 2021) Starship Ship 28 (V1) 200,000 kg (440,925 lb) [6] Mass is a rough estimate, including 100 tons of remaining propellant.
The cosmic web — ribbons of gas and dust tying galaxies together — are the largest structures in the Universe, and a new study shows they are growing hotter over time.
The spread of velocities for the individual galaxies is about 150 km/s. However, this definition should be used as a guide only, as larger and more massive galaxy systems are sometimes classified as galaxy groups. [4] Groups are the most common structures of galaxies in the universe, comprising at least 50% of the galaxies in the local universe.
The word galaxy is derived from the Greek galaxias (γαλαξίας), literally "milky", a reference to the Milky Way. Galaxies range in size from dwarfs with just a few billion (109) stars to giants with one hundred trillion (1014) stars, each orbiting its galaxy's center of mass.
