PHOTOS: 'Ring of fire' solar eclipse

This combination shot shows the progress of the annular solar eclipse over Tokyo, Japan.

In this type of eclipse, the moon passes in front of the sun but doesn't block it entirely, leaving a glowing "ring of fire" around its outer edge.

Sky watchers all over the eclipse's path gathered to enjoy the rare sight. It's the first time an annular solar eclipse has been visible from the US since 1994.
