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 Big Bang model begins with a point of infinite density where the laws of physics break down. This is a deep theoretical problem that suggests the beginning of the Universe is not fully understood, ...

The cosmic optical background (COB) is the summed emission from all sources outside of our Milky Way galaxy emitted at wavelengths roughly corresponding to those visible with the human eye.

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

The earliest light in the universe has been traveling across space since just after the Big Bang. Known as the cosmic ...

The Cosmic Background Explorer (COBE) launched in 1989. One of its instruments measured the intensity of the microwave glow at wavelengths ranging from 0.1 to 10 millimeters across the entire sky.

Various large-scale astrophysical research projects are set to take place over the next decade, several of which are so-called cosmic microwave background (CMB) experiments. These are large-scale ...

“The cosmic microwave background (CMB) was generated 380.000 years after the big bang, when the universe became transparent. The photons we will measure next week were generated a little bit ...

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 ...
