In 1965, American physicists Arno Penzias (1933–) and Robert Wilson (1936–) announced the discovery of microwave radiation, which uniformly filled the sky and had a blackbody temperature of about 3.5K. The pair had been testing a new...

In 1964, a pair of radio astronomers, American physicist Robert Wilson (1936-) and German-born physicist Arno Penzias, working for the Bell Telephone Laboratories in Holmdel, New Jersey, stumbled upon the best evidence in existence to support the big...

The 1965 discovery of cosmic background radiation by Arno A. Penzias and Robert W. Wilson provided important evidence in support of big bang based cosmological models first proposed after American astronomer Edwin Hubble's (1889-1953) discovery that...

Electromagnetic radiation, mostly in the microwave range, believed to be the highly redshifted residual effect (&see; redshift) of the explosion billions of years ago from which, according to the big-bang model, the universe was created. It was...

In cosmology, the cosmic microwave background radiation (most often abbreviated CMB but occasionally CMBR, CBR or MBR, also referred to as relic radiation) is a form of electromagnetic radiation discovered in 1965 that fills the entire universe.[1] It...
