Millions of Americans had the opportunity to view a rare celestial event Monday, when the moon blocked the sun, forming a total solar eclipse.
Aug. 21's event marked the first total solar eclipse that will cross the United States since 1918 and the first total solar eclipse to be seen in the contiguous U.S. since 1979.
Totality will end at 2:48 p.m. EDT near Charleston, South Carolina, according to NASA.
Even for those not in the path of totality, the opportunity to experience a partial solar eclipse will be one worth stepping outside for. However, be sure to wear the proper solar eclipse glasses to protect your eyes from the sun.
Follow along with our live coverage below as the eclipse unfolds across the country.
