Astronomers and the general public have wondered for ages whether other worlds like the Earth exist, and whether the story of the formation of our own Solar System (as we now understand it) is typical.  We are fortunate to live in a time in which we can replace inconclusive debate with observation.  Towards that end, NASA’s Kepler Mission was designed to detect the shadows of Earth-size planets in the Habitable Zone, in which planets orbit at just the right distance from their Sun-like stars for liquid water to exist.  Dr. Jeffrey Van Cleve will talk about our steady progress towards reliably detecting such planets in the 3 years of the mission to date, and the important role of multiplanet transiting systems in validating planet detections and measuring the mass of planets as well as their size-hence opening the door to rich speculation about their composition and history.  He will then explore Kepler’s historical context, looking deep into the past at Kepler’s historical lineage among stargazers, calendars, and the societies that have supported them, with examples drawn from his own travels to the Yucatan, Denmark, Chaco Canyon, and Egypt.  Van Cleve then inverts Kepler’s contemporary significance — Earthlings seeking habitable world — by discussing SETI searches of the ecliptic for inhabited worlds seeking Earthlings, alien worlds which became aware of our planet with their own version of Kepler.  He concludes by looking deep into the future, by discussing how the prevalence of habitable worlds as measured by Kepler informs prospects for interstellar communication and travel. 

Speaker Bio: 

Like Allen Ginsberg, Dr. Jeffrey Van Cleve was born in Newark, New Jersey and has enjoyed living in Boulder, Colorado as well as the Bay Area.  He started his astronomy career at Cornell University with the Infrared Spectrograph of the Spitzer Space Telescope, which he used to study asteroids and the icy moons of the outer Solar System.  After Spitzer, he was a focal plane and systems engineer at Ball Aerospace, where he worked on the Deep Impact, Pluto New Horizons, and Kepler missions.  He is currently at the NASA Ames Research Center, where he works on Kepler and SOFIA, the Stratospheric Observatory for Infrared Astronomy.  He enjoys running barefoot on wet sand, philosophical discussions with friends in Alpine meadows, and marveling at how the ancients knew so much when they had so little by our standards.
