Astronomers claim to have found new evidence supporting a controversial observation that our galaxy is residing in an ...

Professor Emeritus of Physics at the University of Washington used some fancy technology (WMAP data on the cosmic microwave background with a Mathematica calculation) to produce the sound of the Big ...

(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 cosmic microwave background — the leftover light from when the universe was only 380,000 years old — soaks the entire cosmos, filling every cubic centimeter.

The cosmic microwave background is the oldest light in the Universe, emitted about 380,000 years after the Big Bang. It corresponds to the moment when the Universe became cool enough for electrons and ...

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 Universe.

New Cosmic Microwave Background Measurements Sharpen Puzzling "Hubble Tension" Observations with the South Pole Telescope have revealed an independent addition to the biggest problem in cosmology.

And the entire universe was shrouded in neutral hydrogen gas. Then, perhaps 100 million years or so in, everything started to ...

Cosmic microwave background is the oldest light in the universe. It was set free when the universe was a mere 380,000 years old and provides a window to the early universe.
