Cosmologists have known for decades that only a sliver of the universe is made of the same stuff as people, planets, and pets. Analyses of the cosmic microwave background by the Planck satellite ...

(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 cosmic microwave background (CMB) is the faint afterglow of the Big Bang that still bathes the sky in microwave light. For decades, scientists have combed this signal for tiny twists called ...

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 ...

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.

An international research group has created the most detailed and accurate image of the earliest epoch of the universe that we can see to date. The data on the cosmic microwave background ...

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 ...

New research by the Atacama Cosmology Telescope (ACT) collaboration has produced the clearest images yet of the universe's infancy—the earliest cosmic time yet accessible to humans. Measuring ...

Scrutinizing the cosmic microwave background has enabled scientists to search for exotic particles too light to be found any other way. Image Credit: Planck Collaboration/European Space Agency ...
