Introduction to the Blue Moon
The term “blue moon” refers to an unusual phenomenon in lunar cycles, capturing the attention of astronomers and enthusiasts alike.

With its next appearance anticipated, understanding its significance enhances its allure.
What is a Blue Moon?
Traditionally, a blue moon is defined in two main ways: either as the second full moon occurring in a single calendar month or as the third full moon in a season that has four full moons instead of the usual three. The term has seeped into popular culture, largely influenced by the 1947 song ‘Blue Moon,’ but its astronomical definition is what intrigues scientists and the public.

Several planetarium shows and public observatory events are often scheduled during a blue moon, allowing everyone to engage with this rare phenomenon.
