G.Gillet/ESOThe "Pink Moon" this Good Friday will not look pink. Why won't the "pink moon" look pink? There is only one phenomenon that sometimes makes the moon look pink, and that is a total lunar eclipse, commonly known as a "blood moon." However, astronomers refer to a blue moon as a "seasonal blue moon," which is defined as being the third full moon of a season that contains four full moons. The next full moon on May 18, 2019, is a "seasonal blue moon" and looks set to be called the "'Blue Flower Moon".
