On April 8, 2024, the U.S. will witness a total solar eclipse, when the moon moves in front of the sun to cause daytime darkness and a chance to see the sun's corona. The last time that happened in the U.S. was on August 21, 2017, and memories are fresh.
Seven years ago, the path of totality was relatively remote. This time, it will pass by some vast cities and metropolitan areas, ranging northeast from Texas through Maine. Only from within this path will it be possible to witness totality for up to 4 minutes and 26 seconds.
