Every year, near the equinox, NASA's Goddard Space Flight Center in Greenbelt, Md. hosts -- and encourages other museums and educators to host -- a solar extravaganza called Sun-Earth Day. The day is part of a year-long thematic event celebrating sun science. The theme this year is Ancient Mysteries; Future Discoveries.
