A blue supermoon will rise on Wednesday, August 30.
A somewhat rare occurrence, the next blue supermoon won't appear until 2037.
Similar to Strawberry Moons and Pink Moons, a Blue Moon isn't named for its color.
Instead, as the phrase "once in a blue moon" suggests, it's all about timing.
Blue Moons are less common: Only one in about 33 moons qualifies.
