U.S.-LOS ANGELES-SOLAR ECLIPSE

LOS ANGELES, Aug. 21, 2017 -- People attend a solar eclipse viewing event at the Griffith Observatory in Los Angeles, the United States, on Aug. 21, 2017. A once-in-a-century total solar eclipse is spanning the continental United States on Monday, creating a 70-mile-wide (112 kilometers) path of totality stretching from Oregon in the Pacific Northwest to South Carolina on the Southeast Coast. Observers outside the path of totality will see only a partial solar eclipse where the moon covers part of the sun's disk. (Xinhua/Zhao Hanrong via Getty Images)
