The Simons Observatory is one of the most ambitious cosmic observatories on Earth, dedicated to studying the cosmic microwave ...

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

Leftover light from the young universe has a major flaw, and we don't know how to fix it. It's the cold spot. It's just way too big and way too cold. Astronomers aren't sure what it is, but they ...

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 ...

“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 ...

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 ...

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 ...
