There are two definitions of a Blue Moon in astronomy; both are a type of full moon. If the moon actually looks blue, it's caused by a rare type of dust in the atmosphere.

The term 'once in a blue Moon' means that that something is very rare. But just how rare, depends on your definition.
In astronomy, a Blue Moon is a full Moon, which doesn't quite fit in with the months in our calendar. However, there are two completely different ways of calculating which full Moon is a Blue Moon.
Two definitions 1.Blue Moon = The third full Moon in an astronomical season with 4 full Moons (versus the normal 3) 2.Blue Moon = The second full Moon in a month with two full Moons
