Each year around the time of the spring equinox NASA calls attention to the unique relationship between Earth and our Sun. This year, thanks to generous funding by NASA to support the Museum’s science teacher professional development efforts, we’re joining in with our own celebration. This event features hands-on activities, “Cycles of the Sun” planetarium shows, and research demonstrations targeted at a family audience. There will be a particular focus on how solar variability affects human activities and the habitability of Earth. If weather permits, you will have a chance to safely view the Sun and the waxing gibbous Moon through telescopes.
