Planet Hunter Geoff Marcy to Give Annual John N. Bahcall Public Lecture Dec. 11View this image

Dr. Geoffrey Marcy, professor of astronomy at the University of California, Berkeley, will deliver the annual John N. Bahcall Public Lecture at 7:30 p.m. on Tues., Dec. 11, 2007 at the Smithsonian National Air and Space Museum's Lockheed Martin IMAX Theater.

The National Air and Space Museum building on the National Mall in Washington, D.C., is located at Sixth Street and Independence Avenue, S.W. Dr. Marcy will discuss conditions that would need to be present for life to exist on other planets in a talk titled "New Worlds, Yellowstone, and Life in the Universe." Guests attending this free lecture will learn how extreme forms of life found at Yellowstone National Park can teach of the harsh conditions in which life can exist on other planets.

Dr. Marcy's research has focused on the detection of planets around stars other than our Sun. His team has discovered 145 extrasolar planets (as of Nov. 2007), allowing study of their masses and orbits. Among the planets discovered are the first multiple-planet system, the first Saturn-mass planet, the first Neptune-mass planet, and the first transiting planet.

Professor John N. Bahcall (1934-2005) championed the Hubble Space Telescope from its infancy to its ultimate scientific success. He was a tireless and enthusiastic advocate of the project for over three decades-before the scientific community, before NASA, and before Congress. His leadership and commitment were seminal in making the dream of the Hubble Space Telescope a reality.

The John N. Bahcall Annual Public Lecture Series was inaugurated as a commemorative event in 2006 and is organized and made possible by the Space Telescope Science Institute, Baltimore, Md. and the Hubble Space Telescope Program at the Goddard Space Flight Center, Greenbelt, Md. The lecture is the most prestigious part of the Space Telescope Science Institute's Distinguished Visiting Scientists Program.
