Recent constraints on anisotropic cosmic birefringence enhance our understanding of CMB polarization and its implications for ...

The hot debate The favored explanation for the strange nature of the cold spot is that it's due to a gigantic cosmic void sitting between us and the CMB in that direction.

As they reported in a study in Physical Review Letters, researchers from the University of Manchester searched for hints by comparing the distribution of galaxies to the cosmic microwave ...

The cosmic microwave background offered a new window into the nature of reality, one into which astronomers have been peering intently ever since.

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.

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

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

"This is a watershed moment for cosmic microwave background cosmology," said Tom Crawford, deputy director of the South Pole Telescope and research professor at the University of Chicago.

To push back the veil of the Cosmic Microwave Background (CMB) will require unprecedented millimeter-wave measurements of its polarization. The aim is to detect minute patterns in this remnant ...

Cosmic microwave background data support cosmology’s standard model but retain a mystery about the universe’s expansion rate.

Larger-scale fluctuations are also imprinted on the cosmic microwave background, or CMB — the faint radiation left over from the Big Bang.
