An eclipse occurs when one heavenly body such as a moon or planet moves into the shadow of another heavenly body. The next total solar eclipse to visit North America comes on April 8, 2024. The duration of totality will be up to 4 minutes and 27 seconds.

What is a Solar Eclipse?
Sometimes when the Moon orbits Earth, the Moon moves between the Sun and Earth. When this happens, the Moon blocks the light of the Sun from reaching Earth. This causes an eclipse of the Sun, or a solar eclipse. During a solar eclipse, the Moon casts a shadow onto Earth.
There are three main types of solar eclipses:
Total solar eclipse: A total solar eclipse is visible from a small area on Earth. The people who see the total eclipse are in the center of the Moon's shadow when it hits Earth. The sky becomes very dark, as if it were night. For a total eclipse to occur, the Sun, Moon and Earth must be in a direct line.
Partial solar eclipse: This happens when the Sun, Moon and Earth are not exactly aligned. The Sun appears to have a dark shadow on a small part of its surface.
Annular (an-yə-lər) solar eclipse: An annular eclipse happens when the Moon is farthest from Earth. Because the Moon is farther away, it seems smaller. It does not block the entire view of the Sun. The Moon in front of the Sun looks like a dark disk on top of a larger Sun-colored disk. This creates what looks like a ring around the Moon.
During a solar eclipse, the Moon blocks the sunlight to Earth. The Moon also casts a shadow onto Earth.
During a solar eclipse, the Moon casts two shadows on Earth.
The umbra (əm-brə): This shadow gets smaller as it reaches Earth. It is the dark center of the Moon's shadow. People standing in the umbra will see a total eclipse.
The penumbra (pə-ˈnəm-brə): The penumbra gets larger as it reaches Earth. People standing in the penumbra will see a partial eclipse.
Solar eclipses happen every 18 months somewhere on Earth. Unlike lunar eclipses, solar eclipses last only a few minutes.
Never look directly at the Sun: Doing so can permanently damage your eyes! You must use proper safety equipment to look at any type of solar eclipse.
