A new look at radio maps of the sky shows a pronounced tilt, called a dipole, that astronomers are still unable to explain ...

The cosmic microwave background (CMB) radiation originated about 300,000 years after the Big Bang. The CMB's light, initially near-infrared, is now microwave radiation due to the universe's expansion.

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 ...

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 ...

When space telescopes blazed with high-energy radiation for hours earlier this year, astronomers suspected that they were ...

A glow undetectable to the human eye permeates the universe. This light is the remnant signature of the cosmic beginning — a dense, hot fireball that burst forth and created all mass, energy, and time ...

NASA measures radiation over Greenland to improve aviation safety and validate models that predict cosmic doses polar flight ...

The newly detected gravitational wave background could be the result of supermassive black hole binaries that orbit each other for a few million years before merging. By now you’ll have seen the news ...

“They paved paradise and put up a parking lot.” That might be stretching things a bit, especially when the “paradise” in question is in New Jersey, but there’s a move afoot to redevelop the site of ...

Astrophysicists from the Universities of Oxford and Rome have for the first time found evidence of ripples in the Universe’s primordial sea of neutrinos, confirming the predictions of both Big Bang ...

At least for me, the most interesting thing in the popular superhero TV show WandaVision is the brief mention of the cosmic microwave background (CMB). It happens in Episode Four, "We Interrupt This ...
