How often total solar eclipses happen — and why Monday’s was so rare


On April 8th, a rare total solar eclipse drew one “path of totality” over North Americaleaving areas of the United States, Canada and Mexico in darkness in the middle of the day.

A solar eclipse occurs when the moon passes between the Earth and the sun, blocking our view of the sun as it passes. It’s called a total solar eclipse when the moon completely blocks the sun’s light. These events are rare and can only be displayed in specific areas for short periods of time.

The path of totality for the 2024 total solar eclipse stretched from Texas to the East Coast. Cities including Dallas, Texas; Buffalo, New York; and Burlington, Vermont, were among the areas with the best views.

How often do total solar eclipses happen?

Total solar eclipses are rare, and those visible in the United States are even rarer.

Events occur every year or three somewhere on the globe, but are often only visible at the Earth’s poles or in the middle of the ocean.

Several factors contribute to enjoying a total solar eclipse. Viewers need clear skies to ensure the phenomenon is not blocked by clouds, and only those in the path of totality will see the full effect of the sun being blotted out. Those outside the path of totality can still observe a partial eclipse, when the moon covers part, but not all, of the sun, NASA said.
