Are We Alone? 29 Mar 2010, 07:00 UTC ENCORE Hello! Is anyone out there? As the scientific search for extraterrestrial intelligence marks its 50th anniversary, there’s been no contact as yet with alien beings. But SETI researchers maintain that we are not alone. Find out why in a SETI retrospective that looks at the past and future of the search.We remember the first scientific SETI search… Carl Sagan… how the SETI Institute began… the WOW signal…and the 1993 NASA budget cuts.We’ll also hear from critics of the search… scientists involved in optical SETI and SETI@home. Plus, international collaborations… and where the search is headed. Guests: Frank Drake – Director of the Carl Sagan Center for the Study of Life in the Universe, SETI Institute Jill Tarter – Director of the Center for SETI Research, SETI Institute Tom Pierson – CEO, SETI Institute Paul Horowitz – Physicist, electrical engineer, Harvard University Dan Werthimer – Chief Scientist, SETI@home, University of California, Berkeley Ben Zuckerman – Physicist, Astronomer, UCLA Descripción en español
Science@NASA podcast 28 Mar 2010, 06:00 UTC Every day, a NASA infrared space telescope named "WISE" is discovering hundreds of previously unknown asteroids. The observatory is making a remarkable contribution to the census of dark space rocks that could potentially threaten Earth. Please vote for this podcast at PodcastAlley! Get this podcast story.
Are We Alone? 15 Mar 2010, 07:00 UTC Physics means getting physical if you’re tackling the biggest, most mysterious questions in the universe. Stoic scientists endure the driest, darkest, coldest spots on the planet to find out how it all began and why there’s something rather than nothing. From the bottom of an old iron mine to the top of the Andes, we’ll hear their stories.Plus, Steven Weinberg on this weird stuff called dark energy, and Leonard Susskind sees double, no, triple, no, …infinite universes. Guests: Anil Ananthaswamy – Corresponding editor for New Scientist magazine in London and author of The Edge of Physics: A Journey to Earth’s Extremes to Unlock the Secrets of the Universe Steven Weinberg – Nobel Prize-winning physicist at University of Texas at Austin and author of Lake Views: This World and the Universe Leonard Susskind – Professor of theoretical physics, Stanford University André de Gouvêa – Associate professor of physics, Northwestern University Descripción en español
365 Days of Astronomy 15 Mar 2010, 05:00 UTC Julius Caesar and the Calendar Reform, by Zachary Kessin and Julia Smith The 365 Days of Astronomy Podcast is a project that is publishing one podcast per day, 5 to 10 minutes in duration, for all 365 days of 2009. The podcast episodes are written, recorded and produced by people around the world. We are looking for individuals, schools, companies and clubs to provide 5 - 10 minutes of audio for the daily podcast. You can do as few as 1 episode or up to 12 episodes (one per month, subject to our editorial discretion). Our goal is to encourage people to sign up for a particular day (or days) of 2009.
The Planetary Society Radio Podcast 15 Mar 2010, 04:00 UTC HiRISE Principal Investigator Alfred McEwen returns with a report on Mars Reconnaissance Orbiter's super sharp camera and the new HiWish program that lets anyone suggest sites on the Red Planet for imaging. Emily Lakdawalla took advantage of this opportunity. She also recaps some of her recent Planetary Society blog entries. Bill Nye looks foward to President Obama's April space summit. Bruce Betts and Mat Kaplan want to give away
ESOcast 12 Mar 2010, 09:00 UTC Every night, all year round, the ESO Very Large Telescope, or VLT, opens its four giant eyes to scrutinise the beautiful southern skies. Each eye is a huge mirror, 8.2 metres in diameter, that gathers the light of the night sky, and reflects it into optical systems that form ultra-sharp images of the Universe. But keeping the VLT´s eyes clear requires each mirror to be cleaned and recoated occasionally, a delicate and complex procedure.

Silicon Valley Astronomy Lectures 10 Mar 2010, 20:27 UTC A half-century ago, astronomers began trying to "eavesdrop" for radio messages from nearby star systems. However, today, SETI researchers continue to point their telescopes at individual stars, on the assumption that technically advanced societies will inhabit a watery world like our own. Dr. Seth Shostak of the SETI Institute describes these searches, but then discusses some novel ideas for how we might pursue the hunt for "cosmic company" and why it's possible that we might find evidence of sophisticated intelligence out there within only a few decades. Seth Shostak is Senior Astronomer at the SETI Institute, in Mountain View, California and hosts the syndicated radio show called "Are We Alone?" Recorded January 20, 2010.
