Cosmic Optical Background

(COB)
(widespread optical radiation not associated with known sources)

Cosmic Optical Background (COB) radiation is the Visible Light analog to Cosmic Microwave Background (CMB), in the sense of there being optical signal detected in areas between the known sources. As such, it is a portion of the Cosmic Background Radiation (CBR).

Milky Way sources are considered something separate, so the study of COB is hampered by the existence of the Milky Way's Diffuse Galactic Light (DGL).
