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 ...

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 ...

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

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 ...

The image shows the cosmic microwave background radiation visible 380,000 years after the Big Bang. ACT Collaboration; ESA/Planck Collaboration "Before, we got to see where things were, and now we ...

Astronomers discovered cosmic microwave background radiation in the 1960s. The wavelength of this radiation appears to be the same no matter where in space that it comes from and it corresponds to ...
