One year from now, on Monday, 8 April 2024, the moon will pass directly between Earth and the sun, creating a total solar eclipse like the one that crossed the United States from coast to coast on 21 August 2017. As it did that day, the new moon will fully block the sun's bright face, turning day into night for several minutes and revealing the magnificent solar corona, our star's wispy outer atmosphere. Our natural satellite's dark shadow, about 115 miles wide, will cross Mexico, sweep from Texas to Maine, and then darken the Canadian Maritimes. Outside this narrow path, nearly everyone in North America will get a chance to witness a partial solar eclipse.
