A total solar eclipse will sweep across America on August 21, 2017. Tune in to STEM in 30 as we celebrate the Great American Eclipse live from Liberty, Missouri, which is on the Path of Totality. This means that the total solar eclipse will be viewable, weather permitting, and we’ll be there to show it as it happens. We will also be live from the Phoebe Waterman Haas Public Observatory at the National Air and Space Museum in Washington, DC, answering FAQs about eclipses.
