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

The skies will light up Tuesday night with a double lunar phenomenon: the Harvest supermoon and a partial lunar eclipse. Supermoons are full moons that appear larger because they happen in tandem with the lunar orbit’s closest approach to earth.

A partial lunar eclipse happens when the Earth passes between the sun and moon, casting a shadow that darkens a sliver of the moon and appears to take a bite out of it. Since the moon will inch closer to Earth than usual, it’ll appear a bit larger in the sky. The supermoon is one of three remaining this year.
