What is a blue supermoon?
There was a rare, cosmic occurrence in late August. The super blue moon lit up the night sky, capturing people's attention and raising some questions. So what is it? A blue moon is the term for when we see the full moon twice in a single month. Only about 3% of full moons are blue moons, according to NASA. A supermoon is a term for when the moon is closest to Earth. By comparison, the supermoon is much more common-- occurring in about 25% of full moons. But a supermoon that’s also a blue moon? Much more rare. For instance, you'll have to wait until 2037 to see the next one. More LiveNOW from FOX streaming video

The space agency defines a blue moon as the second full moon in a single month. The phrase "once in a blue moon" happens on average every two-and-a-half years.
According to NASA scientists, about 25% of all full moons are supermoons, while only 3% of full moons are blue moons. The occurrence of super blue moons is irregular and can span up to 20 years, with an average of 10 years.

From now until 2024, there will be four supermoons every year. The closest one to the century will occur in December 2052. Additionally, there will be a pair of super blue moons in January and March 2037.
It's unclear where the term "blue moon" came from, but it was first used in a 1937 Farmers' Almanac to describe specific full moons. True blue moons can occur but are rare and caused by atmospheric events.
