For years, cosmologists have argued over a simple question with an awkward answer: How fast is the universe expanding right ...

"The polarized light of the cosmic microwave background is sensitive to new physics that violates parity symmetry," the team ...

(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 ...

What if the Universe were not symmetrical? This idea, which goes against what scientists have long believed, emerges from new studies on large cosmic structures. Instead of being uniform in ...

A proposed five-satellite Cosmic Positioning System could measure cosmic distances directly and help address discrepancies in the Hubble constant through solar system–scale triangulation.

Scientists are reeling from an unexpected blow after news that a much anticipated future observatory—designed to decipher the earliest moments of cosmic history—won’t be able to proceed with its ...

The events surrounding the Big Bang were so cataclysmic that they left an indelible imprint on the fabric of the cosmos. We can detect these scars today by observing the oldest light in the universe.

The cosmic microwave background, shown at left in this illustration, is a flash of light that occurred when the young universe cooled enough for electrons and protons to form the first atoms. It ...

The Atacama Cosmology Telescope’s final data release confirms a major cosmic discrepancy and rules out many attempted solutions.

It was July 1965 when Arno Penzias and Robert Wilson were struggling to explain strange signal noise being picked up by the Bell Labs Holmdel horn radio antenna. They thought at first those damn ...
