Join host Abigail Bollenbach as she walks you through the basics of the cosmic microwave background, the oldest snapshot of the infant universe. A glow undetectable to the human eye permeates the ...

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 ...

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. Two of ...

The Cosmic Microwave Background carries with it a record of events throughout the 13.8-billion-year history of the universe. When you purchase through links on our site, we may earn an affiliate ...

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 ...
