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...

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...

The Far-Infrared Absolute Spectrophotometer (FIRAS) on the COBE satellite, gives different temperatures of the Cosmic Microwave Background. This deviation has a theoretical explanation in the Doppler effect on the dipole (weak) component of the radiation, the true microwave background of the Universe that...

The most detailed snapshots so far of the infant universe are confirming that the cosmos consists mostly of mystery material, called dark energy, that accelerates the universe's expansion. The new evidence comes from the Arcminute Cosmology Bolometer Array Receiver (ACBAR), a South...

Astronomers have stumbled upon a tremendous hole in the universe. That's got them scratching their heads about what's just not there. The cosmic blank spot has no stray stars, no galaxies, no sucking black holes, not even mysterious dark matter. It is 1 billion light...
