Stephenson 2, also known as RSGC2 (Red Supergiant Cluster 2), is a young massive open cluster belonging to the Milky Way galaxy. It was discovered in 1990 as a cluster of red supergiants in a photographic, deep infrared survey by the astronomer Charles Bruce Stephenson, after whom the cluster is named. [2][3] It is located in the constellation ...
Cosmos Redshift 7 (also known as COSMOS Redshift 7, Galaxy Cosmos Redshift 7, Galaxy CR7 or CR7) is a high-redshift Lyman-alpha emitter galaxy. At a redshift z = 6.6, [ 1 ] the galaxy is observed as it was about 800 million years after the Big Bang , during the epoch of reionisation . [ 1 ]
The cosmic microwave background (CMB, CMBR), or relic radiation, is microwave radiation that fills all space in the observable universe. With a standard optical telescope, the background space between stars and galaxies is almost completely dark. However, a sufficiently sensitive radio telescope detects a faint background glow that is almost ...
The Hubble Ultra-Deep Field (HUDF) is a deep-field image of a small region of space in the constellation Fornax, containing an estimated 10,000 galaxies.The original data for the image was collected by the Hubble Space Telescope from September 2003 to January 2004 and the first version of the image was released on March 9, 2004.

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 red object in the center of the zoom-in image is HD1. [1] is a proposed high-redshift galaxy, which is considered (as of April 2022) to be one of the earliest and most distant known galaxies yet identified in the observable universe. The galaxy, with an estimated redshift of approximately z = 13.27, is seen as it was about 324 million years ...
The Sloan Digital Sky Survey or SDSS is a major multi-spectral imaging and spectroscopic redshift survey using a dedicated 2.5-m wide-angle optical telescope at Apache Point Observatory in New Mexico, United States. The project began in 2000 and was named after the Alfred P. Sloan Foundation, which contributed significant funding.
Other designations. CR2-z16-1 [5] CEERS-93316 is a high-redshift galaxy with a spectroscopic redshift z=4.9. [3] Significantly, the redshift that was initially reported was photometric (z = 16.4) and would have made CEERS-93316 the earliest and most distant known galaxy observed. [1][6][7][8] CEERS-93316 has a light-travel distance (lookback ...
