On April 8, 2024, a total solar eclipse will cross North America, passing over Mexico, the United States, and Canada. A total solar eclipse happens when the Moon passes between the Sun and Earth, completely blocking the face of the Sun. The sky will darken as if it were dawn or dusk.
Safety is the number one priority when viewing a total solar eclipse. Be sure you're familiar with when you need to wear specialized eye protection designed for solar viewing by reviewing these safety guidelines.
- After the total solar eclipse on April 8, 2024, the next total solar eclipse that can be seen from the contiguous United States will be on Aug. 23, 2044.
- We can’t normally see the corona – the Sun’s outer atmosphere – because the Sun’s surface below it is so much brighter. But during a total solar eclipse, the corona becomes visible, offering unique opportunities to study it.
- When the Moon completely blocks the visible surface of the Sun during a total solar eclipse, viewers can remove their eclipse glasses. A total solar eclipse is the only type of solar eclipse where eclipse glasses can be momentarily removed.
- When a solar eclipse reaches totality, nocturnal wildlife sometimes wakes up, thinking that it’s nighttime, and non-nocturnal wildlife might think it’s time to head to sleep!
