In the previous three years, 144 90-second Earth & Sky radio shows have been produced under sponsorship of the National Aeronautics and Space Administration. The impact of these shows was explored with a posttest-only experimental design comparing a treatment group that listened to nine daily NASA shows focused on the topic of Antarctica and a control group that listened to nine daily non-NASA shows about whales. Participants were randomly assigned to groups, which did not differ on the variables of gender, age, ethnicity, education, frequency of hearing Earth & Sky, and interest in hearing
NASA cloud observation project. Ground observation reports are compared to cloud information retrieved from satellite instruments in Earth orbit. Learn how to make and report a cloud observation at the time of a satellite overpass. Observations welcome from any interested observers, especially in places where official weather observations are rare. Get satellite overpass times, learn about making observations, report an observation, and explore the database of reported observations (which includes corresponding satellite data once they are available).
Founded in 1999, the Silicon Valley Astronomy Lectures are non-technical illustrated public lectures, presented on six Wednesday evenings during each school year at Foothill College, in the heart of California's Silicon Valley. Speakers over the years have included a Nobel-prize winner, members of the National Academy of Sciences, the first woman in history to discover a planet, an astrophysicist who is an award-winning science fiction writer, and many other well-known scientists explaining astronomical developments in everyday language. The series is jointly sponsored by the Astronomical Society of the Pacific, the SETI Institute, NASA's Ames Research Center, and the Foothill College Astronomy Program. In-kind funding and staff time is contributed by the sponsoring organizations. The lectures are held and videotaped in the 950-seat Smithwick Theater in Los Altos Hills. Thanks to a generous grant from an anonymous local donor, each lecture is now video and audio taped, professionally edited, and made available free of charge on a number of web sites. Videotaped lectures include: * Frank Drake discussing his modern view of the Drake Equation, * Sandra Faber on how galaxies were "cooked" from the primordial soup, * Michael Brown explaining how his discovery of Eris led to the demotion of Pluto, * Alex Filippenko talking about the latest ideas and observations of black holes, * Natalie Batalha sharing the latest planet discoveries from the Kepler mission, * Anthony Aguirre discussing how it is possible to have multiple universes, and * Chris McKay updating the Cassini discoveries about Saturn's moon Titan.
