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.

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 ...

A never-before-seen image of the cosmic microwave background, combining data from the Atacama Cosmology Telescope (ACT) and the Planck satellite, offers a high-definition view of the early Universe.

That’s what Jürgen Sörgel wants to know, asking: “The cosmic microwave background (CMB) was generated 380.000 years after the big bang, when the universe became transparent.

WMAP launched June 30, 2001, with the goal of sensing subtle temperature differences in the cosmic microwave background, the glow of the first atoms to release their radiation 380,000 years after ...

The Cosmic Microwave Background carries with it a record of events throughout the 13.8-billion-year history of the universe. When you purchase through links on our site, we may earn an affiliate ...

Two scientists, Arno Penzias and Robert Wilson, discovered the cosmic microwave background in the mid-1960s while testing a large radio antenna for Bell Laboratories. They detected a constant ...

(via Sabine Hossenfelder) In the Big Bang Theory, the cosmic microwave background — microwave-range radiation that floats through the entire universe at a steady 2.7 Kelvin — is evidence that a hot ...

The cosmic microwave background (CMB) radiation originated about 300,000 years after the Big Bang. The CMB's light, initially near-infrared, is now microwave radiation due to the universe's ...
