The Cosmology Large Angular Scale Surveyor Speaker: Tobias Marriage, Johns Hopkins University The Cosmology Large Angular Scale Surveyor (CLASS) project is an ambitious effort to study the Cosmic Microwave Background (CMB). Its aims to make a unique measurement of CMB polarization that will characterize the conditions during the early universe and help pinpoint when the first stars formed. To accomplish these goals, CLASS researchers have invented and implemented new technologies for telescopes that operate high in the Andes in the Atacama Desert of northern Chile. This international team is led by Johns Hopkins University with key contributions from young researchers. In this lecture Dr. Marriage discusses the science and technology behind CLASS, and provides an update on its progress. - News from the Universe starts at 4:56 - Main talk starts at 20:56 Host: Dr. Frank Summers Recorded live on November 1, 2016 at the Space Telescope Science Institute in Baltimore, MD, USA For more information: http://hubblesite.org/about_us/public_talks
