Skygazers on Tuesday were able to catch a rare celestial phenomenon, a harvest moon, supermoon, and partial lunar eclipse.

Skygazers were treated to a spectacular celestial sight Tuesday night as the orange-ish Harvest supermoon coincided with a partial lunar eclipse.

A supermoon is what happens when a full moon coincides with perigee, or when the moon is closest to the Earth, and it looks bigger than normal.
