Save the date: One year until total solar eclipse sweeps US

The period of total coverage during the solar eclipse is seen near Hopkinsville, Ky. Monday, Aug. 21, 2017. The location, which is in the path of totality, is also at the point of greatest intensity. It’s only a year until a total solar eclipse sweeps across North America. On April 8, 2024, the moon will cast its shadow across a stretch of the U.S., Mexico and Canada, plunging millions of people into midday darkness. (AP Photo/Mark Humphrey, File)
