But there are several important anomalies, including a widely debated one called the Hubble tension. It is named after Edwin ...

Full-Sky Map Of Cosmic Background Radiation, A Full-Sky Map Produced By The Wilkinson Microwave Anisotropy Probe (Wmap) Showing Cosmic Background Radiation, A Very Uniform Glow Of Microwaves Emitted ...

(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 ...

Arecibo Observatory observations of galactic neutral hydrogen structure confirm the discovery of an unexpected contribution to the measurements of the cosmic microwave background observed by the WMAP ...

A new study from an international team of researchers suggests that the universe may be "lopsided", and it could be a huge challenge to our current understanding of the cosmos. The more we have ...

With unique capabilities to track microwave energy fluctuations, a small observatory in the Andes mountains of northern Chile produced maps of 75% of the sky as part of an effort to more accurately ...

With CMB-S4, scientists hope to connect a sandy desert with a polar desert—and revolutionize our understanding of the early universe. In the 1960s, an anomalous, faint electromagnetic glow was ...

The Big Bang theory is supported by the observed expansion of the universe and the cosmic microwave background radiation. The universe's early moments involved a hot, dense state with the formation of ...

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.

Bell Labs built a giant antenna in Holmdel, New Jersey, in 1960. It was part of a very early satellite transmission system called Echo. By collecting and amplifying weak radio signals bounced off ...

Scientists have taken another step toward understanding dark energy by peering through a cosmic cloud of water vapor billions of light-years away from Earth. Dark energy is the name given to the ...
