   Cosmic microwave background radiation

   In cosmology, cosmic microwave background (CMB) radiation (also CMBR, CBR, MBR, and relic radiation) is a form of electromagnetic radiation filling the universe.

   Discovery of cosmic microwave background radiation

   This article concerns the accidental discovery of cosmic microwave background radiation. Although predicted by earlier theories, it was first found accidentally by Arno Penzias and Robert Woodrow Wilson as they experimented with the Holmdel Horn Antenna.

   Timeline of cosmic microwave background astronomy

   1965 - Arno Penzias, Robert Wilson, Bernie Burke, Robert Dicke, and James Peebles discover the cosmic microwave background radiation, eventually confirmed at approximately 2.7K ... 1992 - scientists that analysed data from COBE report the discovery of anisotropy in the cosmic microwave background.

   Cosmic infrared background radiation

   The cosmic infrared background (CIRB) is the radiation from stars in many faint galaxies. ... Cosmic microwave background radiation

   Background radiation

   Background radiation is constantly present in the environment and is emitted from a variety of natural and artificial sources. ... A particular example of this is the cosmic microwave background radiation, a nearly uniform glow that fills the sky in the microwave part of the spectrum; stars, galaxies and other objects of interest in radio astronomy stand out against this background.

   Microwave

   Microwaves are electromagnetic waves with wavelengths ranging from as long as one meter to as short as one millimeter, or equivalently, with frequencies between 300 MHz (0.3 GHz) and 300 GHz. ... Cosmic microwave background radiation

   Extragalactic background light

   The Extragalactic Background Light (EBL) or simply the "extragalactic background" (EGB) is the faint diffuse light of the night sky, consisting of the combined flux of all extragalactic sources. ... Cosmic Microwave Background (CMB) radiation

   Cosmic Background Imager

   The Cosmic Background Imager (or CBI) is a 13-element interferometer perched at an elevation of 5,080 metres (16,700 feet) at Llano de Chajnantor Observatory in the Chilean Andes. It started operations in 1999 to study the cosmic microwave background radiation until 2008.

    Cosmic neutrino background

    The cosmic neutrino background (CνB) is the universe's background particle radiation composed of neutrinos. Like the cosmic microwave background radiation (CMB), the CνB is a relic of the big bang, and while the CMB dates from when the universe was 380,000 years old, the CνB decoupled from matter when the universe was 2 seconds old.
