1. Cosmic background radiation

   Cosmic background radiation is electromagnetic radiation that fills all space. The origin of this radiation depends on the region of the spectrum that is observed. One component is the cosmic microwave background. This component is redshifted photons that have freely streamed from an epoch when the Universe became transparent for the first time to radiation. Its discovery and detailed observations of its properties are considered one of the major confirmations of the Big Bang. The discovery (by chance in 1965) of the cosmic background radiation suggests that the early universe was dominated by a radiation field, a field of extremely high temperature and pressure.The Sunyaev–Zel'dovich effect shows the phenomena of radiant cosmic background radiation interacting with "electron" clouds distorting the spectrum of the radiation. There is also background radiation in the infrared, x-rays, etc., with different causes, and they can sometimes be resolved into an individual source. See cosmic infrared background and X-ray background. See also cosmic neutrino background and extragalactic background light.

1. cosmic background radiation

   Cosmic Background Radiation, also known as Cosmic Microwave Background (CMB), is the residual radiation from the Big Bang, permeating throughout the universe. This relic radiation from about 380,000 years after the Big Bang, provides valuable information about the early stages of the Universe's formation and the physical conditions at that time. It is isotropic to roughly one part in 100,000 and appears uniformly throughout the sky when observed from Earth. Its discovery in 1965 provided strong evidence in support of the Big Bang Theory.
