Dr. Nils Halvorson is in the Live@ studio and sheds light on the DASI telescope at the South Pole. What if we did contact another intelligent life form in the universe? What should we say? What traits best represent our humanity? Douglas Vakoch, the SETI Institute’s Director of Interstellar Message Composition, is working with scientists, artists, linguists, composers, and others to imagine how to speak for our planet. For science fair competition taken to the third power, watch two veteran scientists as they battle head to head to determine who is the Iron Scientist. Home-town favorite, Exploratorium physicist, Dr. Dr. Paul Doherty will square off against heavy-weight contender, visiting Exploratorium Osher Fellow and Boston University astrophysicist Professor Kenneth Brecher. They have 5 minutes to teach their favorite activities, and then move on to the secret ingredients: marbles and panty hose The first-ever live event inside the NASA clean room, where space hardware is being prepared for the Hubble Space Telescope. We'll get dressed in "bunny suits" to explore the room and show you the activities of engineers and scientists getting ready for the next Hubble servicing mission in November. Hubble's pictures have changed our understanding of the galaxy. Here we meet scientists who show us how their images have led to new discoveries, then check in on our own imaging project and track its progress. How much time does an astronomer need to get that great picture? We'll talk with scientists about how they determine their experiments, and learn what it takes to make their case for a few minutes of the telescope's time.
