Eclipses
NASA studies solar eclipses on the ground, in our atmosphere, and in space, influencing solar and Earth science.
An eclipse is an awe-inspiring celestial event that drastically changes the appearance of the two biggest objects we see in our sky: our Sun and Moon. On Earth, people can experience solar eclipses when Earth, the Moon, and the Sun line up.
Safety is the number one priority when viewing a solar eclipse. Be sure you're familiar with and follow these safety guidelines when viewing an eclipse.

Quick Facts
An eclipse season is one of only two periods during each year when the Sun, the Moon, and Earth are aligned, allowing eclipses to occur. Each season lasts about 35 days and repeats just short of six months later!
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 emerges, offering unique opportunities to study it.
