CL 1358+62 (ClG 1358+62) is a galaxy cluster located at z.
In standard cosmology, comoving distance and proper distance are two closely related distance measures used by cosmologists to define distances between objects.
Distance measures are used in physical cosmology to give a natural notion of the distance between two objects or events in the universe.
In astronomy, an epoch is a moment in time used as a reference point for some time-varying astronomical quantity, such as the celestial coordinates or elliptical orbital elements of a celestial body, because these are subject to perturbations and vary with time.
Giga is a unit prefix in the metric system denoting a factor of a (short-form) billion (109 or 000).
The light-year is a unit of length used to express astronomical distances and measures about 9.5 trillion kilometres or 5.9 trillion miles.
This article documents the most distant astronomical objects so far discovered, and the time periods in which they were so classified.
In physics, redshift happens when light or other electromagnetic radiation from an object is increased in wavelength, or shifted to the red end of the spectrum.
Triangulum is a small constellation in the northern sky.
The W. M. Keck Observatory is a two-telescope astronomical observatory at an elevation of 4,145 meters (13,600 ft) near the summit of Mauna Kea in the U.S. state of Hawaii.
