A new map offers clues about the beginning of the universe

Last month, scientists created a new, more detailed map of that low background rumble of radiation in our universe. The U.S. National Science Foundation's Cosmology Large Angular Scale Surveyor—or CLASS—a collaboration led by Johns Hopkins University astrophysicists, created the maps. 
Joseph Eimer is a senior scientist on the CLASS project and the lead author of the study published in The Astrophysical Journal.
