In recent years, people have been using the name Blue Moon for the second of two full moons in a single calendar month. An older definition says a Blue Moon is the third of four full moons in a single season. Someday, you might see an actual blue-colored moon. The term once in a blue moon used to mean something rare. Now that the rules for naming Blue Moons include several different possibilities, Blue Moons are pretty common! The next one will be on May 21, 2016, and this Blue Moon – blue in name only – will be near the red planet, Mars. Follow the links below to learn more about Blue Moons
