In cosmology, the cosmic microwave background radiation is a form of electromagnetic radiation discovered in 1965 that fills the entire universe. It has a thermal 2.725 kelvin black body spectrum ...

The cosmic microwave background (CMB) is primeval radiation emitted shortly after the Big Bang. Regarded as an 'echo' of the Big Bang, CMB fills the universe.

This first light is called the "Cosmic Microwave Background (CMB)," leftover radiation which is spread almost evenly through the universe.The CMB carries with it the signatures of the physical ...

In the Big Bang Theory, the cosmic microwave background — microwave-range radiation that floats through the entire universe ...

The standard model of cosmology relies on an accurate reading of the cosmic microwave background. This radiation, emitted 380,000 years after the Big Bang, is considered proof of the theory's ...

Astronomers discovered cosmic microwave background radiation in the 1960s. The wavelength of this radiation appears to be the same no matter where in space that it comes from and it corresponds to ...

This afterglow—the "cosmic microwave background" (CMB), the relic radiation left behind by the Big Bang—has given astronomers insights into the birth of the universe and helped shape the ...

The Cosmic Microwave Background radiation, or CMB for short, is a faint glow of light that fills the universe, falling on Earth from every direction with nearly uniform intensity.
