The Solar Dynamics Observatory (SDO), which NASA launched in February 2010, is a "sun-pointing semi-automatic spacecraft," a mini space observatory that is designed to study the sun so that scientists may better understand the causes of solar variability and its effects on Earth. For educators who are teaching about the power of our solar system's only star, or for anyone interested in breaking research on the sun, this is a fascinating website. Readers might like to start with the Mission tab, which lists information about the SDO's science, the spacecraft itself, the team that is running the project, and 1968 refereed publications. News & Resources is interesting for its Mission Blog, which offers updates on the mission as instruments are repaired, data is gathered, and conclusions are drawn. The Gallery section also offers some powerful images, animations, and videos of the sun.
