|Venus Transit and the Search for New Worlds (Webcast)|
This webcast features a panel of NASA scientists and engineers discussing the future of extrasolar planet research and the science behind a rare astronomical event: Venus crossing the Sun?s disk for about seven hours on June 8, 2004, an event not seen since 1882. The transit demonstrates a key technique being used to detect planets orbiting stars outside our Solar System. Just as Venus temporarily dimmed the light of the Sun when it crossed in front of it, a distant planet may cross in front of and block the light of its parent star. Several planned missions will hunt for such extrasolar planets as part of NASA's Origins program, which seeks to answer the following questions: Where did we come from? Are we alone?
