365 Days of Astronomy 30 Mar 2010, 05:39 UTC How Far is Far? by Steve Nerlich. Since we can only see distant objects as they appeared in the past - how do we know how far away they are now? 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.
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

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.
