Astronomers Measure the Elusive Extragalactic Background Light


May 24, 2013

Alberto Domínguez Measuring the extragalactic background light (EBL) is no simple task, complicated by the fact that the Earth is lodged inside a bright solar system and a bright Milky Way. Now, a team of astronomers has come up with a solution that ingeniously overcomes the technical challenges of measuring EBL. The researchers propose that one answer to the problem of measuring EBL lies in measuring the attenuation--or weakening--of very-high-energy gamma rays from distant blazars. Full Story
