The Big Bang's Particle Glow

The universe's oldest light hasn't made a pit stop for 13.82 billion years—beginning its journey just 380,000 years after the big bang. That light, the so-called cosmic microwave background (CMB), serves as a familiar hunting ground for astronomers who seek to understand the universe in its infancy. Unfortunately, it also obscures what lies beyond it: the first hundreds of thousands of years of the universe. Now astronomers think they have peeked beyond even the CMB by capturing evidence of neutrinos traveling since the cosmos was just a second old.
