(via Sabine Hossenfelder) In the Big Bang Theory, the cosmic microwave background — microwave-range radiation that floats through the entire universe at a steady 2.7 Kelvin — is evidence that a hot ...

The CLASS telescope array has taken a fresh look at the infant universe to hunt for polarized light in the Cosmic Microwave Background that resembles light bouncing off a cosmic car hood.

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 validity ...

Findings from a new study into the cosmic "afterglow" may rewrite the history of the universe, according to researchers. This afterglow—the "cosmic microwave background" (CMB), the relic ...

The cosmic microwave background (CMB) is the oldest light in the Universe, emitted approximately 380,000 years after the Big Bang. It is microwave radiation that uniformly fills space, a witness to ...

They have accomplished this, not in a laboratory, but in space, using a catalog of over half a billion galaxies imaged by NASA’s Wide-field Infrared Survey Explorer, which flew from 2010 to ...

The Cosmic Microwave Background carries with it a record of events throughout the 13.8-billion-year history of the universe. Just as Charles Darwin once used the fossil record to tell the story of ...

But in 1964, Bell Labs researchers Arno Penzias and Robert Wilson accidentally discovered the microwave remnants of the Big Bang, the cosmic background radiation, using the antenna, earning it a ...
