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 ...

Scientists used Cosmic Microwave Background data to challenge our understanding of the universe's shape. Here's what they ...

New research suggests the universe may be lopsided. Cosmic microwave background and galaxy data hint at directional differences, challenging cosmology’s assumption of uniformity and standard ...

George Smoot, who led the team that first measured tiny fluctuations in the cosmic microwave background, passed away on 18 ...

(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 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.

Repulsive gravity at the quantum scale would have flattened out inhomogeneities in the early universe First light The cosmic microwave background, as imaged by the European Space Agency’s Planck ...

(via Dr. Becky) There's a strange, unexplained feature of the Cosmic Microwave Background which seems to be aligned with the Solar System, and we don't why. Is it real or just a coincidence? And if it ...

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 ...
