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 ...

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

This is the Cosmic Microwave Background, electromagnetic radiation from almost 13.8 billion years ago, immediately after the Big Bang. It’s the border of the known universe. NASA/WMAP Science ...

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

Nearly 400,000 years after the Big Bang, the primordial plasma of the infant universe cooled enough for the first atoms to coalesce, making space for the embedded radiation to soar free. That ...

The primordial cosmic microwave background (CMB) radiation has since traveled some 13.8 billion years through the expanding cosmos to our telescopes on Earth and above it.

That light, the cosmic microwave background radiation (CMBR), comes to us from every direction in the sky, uniform except for faint ripples and bumps at brightness levels of only a few part in one ...

Cosmic microwave background is a sea of radiation that provides us with evidence for the big bang. When around 1916 Einstein first used general relativity to build a cosmic model, he followed 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.
