Conversations host Harry Kreisler welcomes Princeton cosmologist Jim Peebles for a discussion of his intellectual odyssey. They discuss his contributions to cosmology and the future of the field. Series: "Conversations with History" [Humanities] [Show ID: 12061]

Before we get all the way back to the Big Bang, there may have been a time when stars like our Sun and galaxies like our Milky Way did not exist, because the Universe was denser than it is now. Harvard professor Abraham (Avi) Loeb explores how and when the first stars and galaxies formed. Series: "Scientific Horizons" [Science] [Show ID: 22628]

Conversations host Harry Kreisler welcomes Cornell's Steven Squyres for a discussion of the Mars Exploration Rover Mission. Reflecting on the intellectual journey that led to his role in the Mars mission, Squires reminisces about his early years, his education and his career in geology and astronomy. Discussing the role of leadership in a complex scientific project, he compares the characteristics, skill set, and work of scientists and engineers, and he describes the dynamic process that led to the project’s success in exploring Mars. He explains the importance of the mission and what was learned and concludes with thoughts on the future of planetary exploration. Series: "Conversations with History" [Science] [Show ID: 22444]

Steven Squyres, Professor of Astronomy at Cornell University, has participated in a number of NASA's planetary space flight missions, including the Voyager mission to Jupiter and Saturn, the Magellan mission to Venus, the Near Earth Asteroid Rendezvous mission, and the Mars Exploration Rover Project. Here he ponders the future of planetary exploration. Series: "UC Berkeley Graduate Lectures" [Science] [Show ID: 21041]

Steven Squyres, Professor of Astronomy at Cornell University, was the principle scientist behind the Mars Exploration Rover Project. He discusses the engineering challenges that had to be met in getting the rovers to Mars, as well as the scientific results obtained by both vehicles over more than seven years of exploration.

Learn how the local amateur astronomy community in San Diego, particularly the large San Diego Astronomy Association, can help classroom teachers and what hands-on exercises and instructional material would be useful in the classroom. Series: "TeacherTECH" [Science] [Show ID: 20383]

As part of UC San Diego’s Division of Physical Sciences 50th Anniversary Lecture Series, join UC San Diego’s Tom Murphy on an exploration of how his project looking for deviations in Einstein’s theory of general relativity led to the discovery of the Soviet Lunokhod 1 lunar rover that vanished mysteriously nearly 40 years ago.

400 years ago, our world-view changed when Galileo proved that the Earth was not the center of the universe but orbits around the Sun. 15 years ago the world shifted again when the first planets were discovered orbiting other stars. Last year, using adaptive optics and the 10 meter W.M. Keck telescope in Hawaii, a Lawrence Livermore National Lab team produced the first ever picture of another solar system. One day, these techniques may even lead to an image with a pale blue dot circling a nearby star - another Earth. Join LLNL astronomer Bruce Macintosh and Lisa Poyneer as they describe the new technologies that made these pictures possible.
