The Year in Pictures

On the Cover: For those lucky enough to have seen it, the North American Eclipse on August 21, 2017 was a life-changing moment—especially for those viewing a total solar eclipse for the first time. Screams of delight, tears, and cheers erupted across the United States as the eclipse followed its path of totality across the continent. Science was done, people came together, and everyone—even those seeing a partial eclipse—had fun watching Earth’s Moon pass in front of its star. Planetary Society Web Editor Tanya Harrison photographed the eclipse from an altitude of 11.6 kilometers (38,000 feet) on board special Alaska Airlines Flight “Solar 1.” Read Tanya’s account of her experience at <a href="http://planet.ly/chasingtotality">planet.ly/chasingtotality</a>.
