Editor's note:  The next lunar eclipse will be a total lunar eclipse on Sept. 27, 2015. It will occur while the moon is at perigee, making it a rare Supermoon Blood Moon lunar eclipse. Such an event won't happen again until 2033.

A total lunar eclipse occurs when the moon passes completely beneath Earth's shadow.
