Episode 40: Into Darkness: The Study of Dark Energy in the Universe, with Matt Dobbs

Feature Guest: Matt Dobbs Dark energy is described as one of the most mysterious phenomenon in our already generally baffling universe. To help us shed some light in the darkness, Matt Dobbs joins Justin Trottier at The Star Spot. His observations of galaxy clusters at the south pole telescope are at the leading edge of our exploration into the unknown. Current in Space Benjamin reminds us that astronomers get as close as likely possible to working as time travellers - or at least time voyeurs - and recently discovered the furthest - and hence oldest - galaxy in the universe. Then, as if competing for best entries in the Book of Guinness World Records, Anuj and Victoria tell us about the Boomerang Nebula, a place in our galaxy so cold it makes Toronto winters - and even the afterglow of the Big Bang - seem balmy by comparison. And Dave rounds out our news with the announcement of a major milestone in our search for candidate extrasolar planets in our hunt for Earth's twin.  About Matt Dobbs Matt Dobbs is an Associate Professor of Physics and associate member of the Department of Electrical and Computer Engineering at McGill University in Montreal. He is a Canada Research Chair and is a Senior Fellow in the Canadian Institute for Advanced Research Cosmology and Gravity program. He was a recipient of an Owen Chamberlain Fellowship at the Lawrence Berkely Laboratory in 2002 and a Sloan Fellowship in 2009. His work explores the intersection between particle physics and cosmology. His research has brought him to some exotic locations, but none more remote than his observations with the South Pole telescope.
