Let there be light. Otherwise we couldn\u2019t watch a sunset or YouTube. Yet what your eye sees is but a narrow band in the electromagnetic spectrum. Shorten those light waves and you get invisible gamma radiation. Lengthen them and tune into a radio broadcast.\nDiscover what\u2019s revealed about our universe as you travel along the electromagnetic spectrum. There\u2019s the long of it: an ambitious goal to construct the world\u2019s largest radio telescope array \u2026 and the short: a telescope that images high-energy gamma rays from black holes.\nAlso, the structure of the universe as seen through X-ray eyes and a physicist sings the praises of infrared light. Literally.\nAnd, while gravity waves are not in the electromagnetic club, these ripples in spacetime could explain some of the biggest mysteries of the cosmos. But first, we have to catch them!\nGuests:\n\n\nAnil Ananthaswamy \u2013 Journalist and consultant for New Scientist in London\n\n\nHarvey Tananbaum \u2013 Director of the Chandra X-Ray Center, located in Cambridge Massachusetts at the Smithsonian Astrophysical Observatory\n\n\nDavid Reitze \u2013 Executive director of the Laser Interferometer Gravitational Wave Observatory (LIGO), California Institute of Technology\n\n\nAlbert Lazzarini \u2013 Deputy director, LIGO, California Institute of Technology\n\n\nAlan Marscher \u2013 Professor of astronomy at Boston University\n\nDescripci\xf3n en espa\xf1ol\nFirst released March 19, 2012\nLearn more about your ad choices.
