The Cosmic Microwave Background carries with it a record of events throughout the 13.8-billion-year history of the universe.

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.

The cosmic microwave background can help scientists piece together the history of the universe.

The photos show light, dark and the polarization of light—background radiation known as the cosmic microwave background, and details the movement of hydrogen and helium gas at the beginning of ...

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 ...

Scientists are using secondary signatures from the cosmic microwave background to map the universe’s hidden matter.

Just when the search for exoplanets looked like the undisputed fashionable field of study for 2010, the cosmic microwave background (CMB) is stepping to the forefront of astronomy and cosmology ...

As it studies cosmic microwaves, the Simons Observatory in Chile aims to help prove or disprove cosmic inflation, a notion that the universe expanded rapidly in the moment after the Big Bang.

This month marks the 50th anniversary of the discovery of the Cosmic Microwave Background, which is the radiation left over from the birth of the universe.

Perhaps most promising is an upcoming project called the Next Generation Cosmic Microwave Background Experiment, which astronomers hope will shed light on space mysteries like neutrinos, dark ...

This has given scientists their best look yet at the Cosmic Microwave Background (CMB) - the leftover radiation from the Big Bang which fills the entire observable universe.

The fingerprints of the Big Bang are still visible in outer space in what's known as the cosmic microwave background (CMB). But more recent sources of microwaves, like AMEs, mess up that picture.
