It possesses a diffuse core which is the largest core of any galaxy known to date, [5] and contains a supermassive black hole, one of the largest discovered. [5] IC 1101 is located at 354.0 megaparsecs (1.15 billion light-years) from Earth. It was discovered on 19 June 1790, by the German-British astronomer William Herschel. [6]
This is a list of largest galaxies known, sorted by order of increasing major axis diameters. The unit of measurement used is the light-year (approximately 9.46 × 10 12 kilometers). Overview
JADES-GS-z13-0 is a high-redshift Lyman-break galaxy discovered by the James Webb Space Telescope (JWST) during NIRCam imaging for the JWST Advanced Deep Extragalactic Survey (JADES) on 29 September 2022.
JADES-GS-z14-0 is a high-redshift Lyman-Break galaxy in the constellation Fornax that was discovered in 2024 using NIRcam as part of the JWST Advanced Deep Extragalactic Survey (JADES) program. [ 1 ] [ 2 ] It has a redshift of 14.32, making it the most distant galaxy and astronomical object ever discovered.
Voids are immense spaces between galaxy filaments and other large-scale structures. Technically they are not structures. They are vast spaces which contain very few or no galaxies. They are theorized to be caused by quantum fluctuations during the early formation of the universe. A list of the largest voids so far discovered is below.
CGCG 049-033 is an elliptical galaxy, located some 680 million light-years from Earth, [2] in the constellation of Serpens. It is the central galaxy (BCG) of the galaxy cluster Abell 2040. [3] CGCG 049-033 is known for having the longest galactic jet ever discovered. The beam is about 1.5 million light-years long and was discovered in December ...
