Understanding the Blue Supermoon
The term “blue supermoon” refers to a phenomenon where a full moon coincides with a supermoon, which is a full moon that appears larger and brighter due to its proximity to Earth. Typically, a supermoon occurs when the moon is at or near its perigee—the point in its orbit when it’s closest to our planet.
What Makes a Moon ‘Blue’?
A “blue moon” is defined as the second full moon occurring within the same calendar month. This is a rare event in itself. To combine a blue moon with a supermoon creates a striking visual spectacle that captures the imaginations of sky watchers and astronomy enthusiasts alike.
Frequency of Blue Supermoons
The confluence of these two celestial events—where a full moon is both the second of the month (blue) and occurs at perigee (supermoon)—is infrequent. Statistically, blue supermoons happen approximately once every 19 years, but that can vary depending on specific monthly lunar cycles.
Recent and Upcoming Blue Supermoons
- August 2018: The last blue supermoon occurred on August 31, 2018. This event was significant as it marked the first occurrence of a blue supermoon since 2016.
- August 2037: The next predicted blue supermoon will be on August 20, 2037, according to astronomical calculations.
Recent studies indicate that, since the 20th century, the occurrence of blue supermoons has become an even more awaited cosmic event, thanks in part to increased media coverage and accessibility to astronomy.
Why Are Blue Supermoons Significant?
As fascinating as blue supermoons are from an observational standpoint, they also have cultural and historical significance:
- Folklore and Cultural Traditions: Many cultures have myths and legends surrounding the moon. The blue moon has been used to mark unique cultural events and significance.
- Scientific Observation: Astronomers use these events to study lunar cycles and understand more about the moon’s effects on Earth.
