Galactic Background Noise is the name given to the electromagnetic radiation that flows throughout the universe in all directions. It is the last remnant from the formation of the universe (the big bang) and is considered my almost all cosmologists to be proof of big bang theory. It appears as static on an untuned TV or radio, it is quite literally random noise across all frequencies at once.

Galactic Background Noise is measured at around 3ºK and can obscure weak signals from satellites or distant cosmic phenomena (TXF: "Little Green Men").
