Summary: <p><span class="caps">ENCORE</span> Let there be light. Otherwise we couldn’t 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.</p> <p>Discover what’s revealed about our universe as you travel along the electromagnetic spectrum. There’s the long of it: an ambitious goal to construct the world’s largest radio telescope array … and the short: a telescope that images high-energy gamma rays from black holes.</p> <p>Also, the structure of the universe as seen through X-ray eyes and a physicist sings the praises of infrared light. Literally.</p> <p>And, 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!</p> <h2>Guests:</h2> <ul> <li> <strong><a href="http://www.sciencefactory.co.uk/content/authors.php?aid=84">Anil Ananthaswamy</a></strong> – Journalist and consultant for <i>New Scientist</i> in London</li> <li> <strong><a href="http://chandra.harvard.edu/press/bios/tananbaum_bio.html">Harvey Tananbaum</a></strong> – Director of the Chandra X-Ray Center, located in Cambridge Massachusetts at the Smithsonian Astrophysical Observatory</li> <li> <strong><a href="http://www.phys.ufl.edu/~reitze/">David Reitze</a></strong> – Executive director of the Laser Interferometer Gravitational Wave Observatory (<span class="caps">LIGO</span>), California Institute of Technology</li> <li> <strong><a href="http://www.ligo.caltech.edu/~lazz/">Albert Lazzarini</a></strong> – Deputy director, <span class="caps">LIGO</span>, California Institute of Technology</li> <li> <strong><a href="http://www.bu.edu/blazars/AlanMarscher.html">Alan Marscher</a></strong> – Professor of astronomy at Boston University</li> </ul><p><strong><a href="http://www.seti.cl/podcast-del-instituto-seti-atrapar-una-onda/">Descripción en español</a></strong></p> <p>First released March 19, 2012</p>
