Education Around Earth – Andros Island, Bahamas Coral Reef Ecosystem is Living Laboratory for Students
For over 25 years, Dr. Larry Wiedman has led teams of high school and college students in documenting changes in the land and sea environments of Andros Island in the Bahamas. They are particularly interested in studying coral reefs but are intent on not influencing the very changes they are trying to study. Dr. Wiedman is a professor in the biology department at the University of Saint Francis in Fort Wayne, Indiana. Dr. David Mullins, Earthzine’s Associate Editor for Education, interviewed Dr. Wiedman about the project and his thoughts about educating future generations of Earth observers.

Education Around Earth – High School Students Debate Federal Incentives for Alternative Energy
During the week of June 15, 2009, an estimated 3,500 high school students from across the U.S. debated the politics, challenges, advantages, and science of federal incentives for alternative energy at the National Forensic League (NFL) National Speech and Debate Tournament in Birmingham, Alabama. This year’s national topic was, “Resolved: That the United States federal government should substantially increase alternative energy incentives in the United States” and those participating had to win district tournaments in their respective states in order to advance to the national competition.

NASA Image of the Day
Orbital Sunrise
The Expedition 24 crew on the International Space Station photographed this image of polar mesospheric clouds illuminated by an orbital sunrise. Polar mesospheric, or noctilucent ("night shining"), clouds usually are seen at twilight, following the setting of the sun below the horizon and darkening of Earth's surface. Occasionally the station's orbital track becomes nearly parallel to Earth's day/night terminator for a time, allowing the clouds to be visible to the crew at times other than the usual twilight because of the station's altitude. This photograph shows polar mesospheric clouds illuminated by the rising, rather than setting, sun at center right. Low clouds on the horizon appear yellow and orange, while higher clouds and aerosols are illuminated a brilliant white. Polar mesospheric clouds appear as light blue ribbons extending across the top of the image. The station was located over the Greek island of Kos in the Aegean Sea (near the southwestern coastline of Turkey) when the image was taken at approximately midnight local time. The orbital complex was tracking northeastward, nearly parallel to the terminator, making it possible to observe an apparent "sunrise" located almost due north. A similar unusual alignment of the ISS orbit track, terminator position and seasonal position of Earth's orbit around the sun allowed for this striking imagery of over the Southern Hemisphere.
