Cosmic Background Radiation

(electromagnetic radiation coming from every direction)

Cosmic Background Radiation (CBR) radiation is Electromagnetic Radiation (EMR) detectable in all directions. Diffuse Extragalactic Background Light (DEBRA) means more or less the same thing.

Some terms by type of Electromagnetic (EM) radiation:

The term Extragalactic Background Light (EBL) typically is meant to include Microwave, Infrared (IR), Visible Light, and some Ultraviolet (UV).

The same phrase, Cosmic Background Radiation, is occasionally used to mean specifically the CMB.

Analogous is the Cosmic Neutrino (ν) Background (CNB or CvB or Relic Neutrinos).
