Blue Moon 2018 in pictures: Staggering photos of last nights Blue Moon

Astronomy specialists say 2037 is the next time we could enjoy a blue moon. A full moon usually graces the skies just once a month.

Because February only had 28 days, this year's full moon carried over to March, confirming the March 31 full moon would be a "blue" one. The peak came at 8:37 a.m. this morning, but with clear skies expected tonight, there will be plenty of blue full moon waiting to shine.

Sky watchers should not miss the chance the see the blue moon this Easter weekend. The first full moon for the month of March was however visible on 2 of March. The moon does not turn blue. The moon circles Earth every 27 days, but the geometry of the positioning of the Earth, sun and moon is the same every 29.5 days.

The monthly blue moon is the second full moon in a month with two full moons. This full Moon is referred to as the Paschal full Moon. The moon appeared blue because of all the dust the volcano lofted into the air.

Today's full moon, which is the first full moon of spring, is also known as a "Paschal Moon", which is the full moon right before Easter Sunday. The first Sunday after the Paschal Moon is celebrated as Easter Sunday, as it is the case this year.

Both the January and March 2018 Blue Moons are blue in name only. Due to the fact that it happened twice this year, we won't see the phenomenon again until 2020.

Because a blue moon is quite rare, the lunar event helped to coin the saying "once in a blue moon". That left the short month of February with no full moon, setting the phase for March's two full moons. One alternative name is the Full Sap Moon, as this is the time of year when the sap of sugar maples starts to flow.
