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.
Linda Sparke. Linda Siobhan Sparke is a British astronomer known for her research on the structure and dynamics of galaxies. She is a professor emerita of astronomy at the University of Wisconsin–Madison, [1] and Explorers Program Scientist in the NASA Astrophysics Division. [2]
Ordinary (baryonic) matter (4.9%) Dark matter (26.8%) Dark energy (68.3%) [6] The observable universe is a ball-shaped region of the universe consisting of all matter that can be observed from Earth or its space-based telescopes and exploratory probes at the present time; the electromagnetic radiation from these objects has had time to reach ...
SA (rs)b, H II Sy2 [1] Apparent size (V) 6.9 × 3.7 moa [1] Other designations. NGC 4501, UGC 7675, PGC 41517, VCC 1401 [1] Messier 88 (also known as M88 or NGC 4501) is a spiral galaxy about 50 to 60 million light-years away from Earth [3][4][5] in the constellation Coma Berenices. It was discovered by Charles Messier in 1781.
GN-z10-1, [4] GNS-JD2 [3] GN-z11 is a high-redshift galaxy found in the constellation Ursa Major. It is among the farthest known galaxies from Earth ever discovered. [5][6] The 2015 discovery was published in a 2016 paper headed by Pascal Oesch and Gabriel Brammer (Cosmic Dawn Center). Up until the discovery of JADES-GS-z13-0 in 2022 by the ...
The results of the study were published in the journal Nature. “This discovery unveils the crucial role played by ultra-faint galaxies in the early Universe's evolution,” Iryna Chemerynska, an ...
The Condor Galaxy is a colossal spiral galaxy disturbed by the smaller IC 4970. It is the largest known spiral galaxy with the isophotal diameter of over 717,000 light-years (220 kiloparsecs). [1] Galaxies are vast collections of stars, planets, nebulae and other objects that are surrounded by an interstellar medium and held together by gravity.
The Milky Way is an example of a spiral galaxy. It is estimated that there are between 200 billion [7] (2 × 10 11) to 2 trillion [8] galaxies in the observable universe. Most galaxies are 1,000 to 100,000 parsecs in diameter (approximately 3,000 to 300,000 light years) and
