Pictured here is a solar eclipse as seen from space and land on March 29, 2006. A solar eclipse offers a good opportunity to study the corona, or outer atmosphere, of the sun. NASA combines the “vantage point” of the space-based Solar Heliospheric Observatory (SOHO) with the image of the corona as recorded by the Williams College Eclipse Expedition to Kastelorizo Island, Greece. It is only during a solar eclipse that people on Earth can see the corona of the sun, which is highlighted here. SOHO was launched in 1995 as part of an international collaboration to study the sun.
