When the moon's shadow falls on Earth, observers within that shadow see the moon block a portion of the sun's light.
The MODIS instrument on NASA's Aqua satellite captured this image of the total solar eclipse moving across the south Pacific Ocean at 03:05 UTC on March 9, 2016. NASA's Terra satellite also imaged the eclipse on the morning of March 9 at 01:40 UTC.
