On April 8, 2024, a total solar eclipse will be visible in parts of Mexico, the U.S. and Canada, and all of North America will see at least a partial solar eclipse. The maximum length of totality — when the sun's face is completely blocked by the moon — will be 4 minutes, 28 seconds, which will occur close to the village of Nazas in northwestern Mexico. That's relatively long, but it's nowhere near the record.
So what is the longest total eclipse in history? And what's the longest possible total solar eclipse?
