Welcome to the July 2007 episode of Blueshift, from NASA Goddard Space Flight Center. Catch up on the latest astronomy headlines, and listen to our audio scrapbook from the American Astronomical Society meeting in Hawaii. For this episode, we interviewed Dr. John Mather, co-winner of the 2006 Nobel Prize in Physics. Dr. Mather talks about cosmology, NASA missions, winning the Nobel Prize, and his induction into a little-known Swedish student organization. We've also got a new brain teaser - and we're eagerly awaiting your answers at our website!
