May's celestial double feature is a sight to behold, offering sky-gazers a unique opportunity to witness two full moons in a single month. The first, dubbed the Flower Moon, peaks at 1:23 p.m. ET on Friday, but its full splendor can be observed from Thursday night through Saturday. This moon rises low in the east at sunset, reaches its highest point around midnight, and sets low in the west before sunrise on Saturday. Noah Petro, project scientist for the Artemis III mission, notes that the moon will appear full for 24 hours around this peak moment, providing ample time for sky-gazers to appreciate its beauty.
What makes this event particularly fascinating is the fact that it marks the beginning of a series of three micromoons. Micromoons occur when the full moon reaches apogee, or its greatest distance from Earth, resulting in a slightly smaller and dimmer appearance. The Flower Moon will be 249,180 miles away from Earth, compared to its average distance of 238,855 miles. This phenomenon is not only visually captivating but also scientifically intriguing, as it provides an opportunity to study the moon's behavior at different distances from our planet.
The second full moon of the month, known as the Blue Moon, will peak and appear fullest at 4:45 a.m. ET on May 31 before the sun rises. This is a calendrical blue moon, which occurs when a month starts and ends with a full moon, a rare event that happens seven times every 19 years. The term 'blue moon' has an interesting history, originating from a 16th-century expression 'the moon is blue,' referring to something impossible. However, after the eruption of the Krakatoa volcano in Indonesia in 1883, people reported seeing strangely colored sunsets and a 'blue moon,' which may have actually been a result of the Earth's atmosphere containing dust or smoke particles.
The Flower Moon also holds cultural significance, as it is named after the Comanche tribe, who associate it with the blooming of wildflowers across North America. Indigenous tribes have various names for this full moon, including the Strawberry Moon for the Potawatomi and Shawnee, and the Mulberry Moon for the Choctaw and Creek. These names reflect the cultural connection between the moon and the natural world, particularly the ripening and harvesting of fruits and berries.
The Flower Moon is also a symbolic reminder of the Artemis II mission, which saw four astronauts embark on a 10-day trip around the far side of the moon in April. The crew members expressed their sentiment during the mission as 'moon joy,' and the Flower Moon provides an opportunity to relive that excitement. Even from more than 200,000 miles away, sky-gazers can appreciate the moon just as the Artemis II crew did, capturing awe-inspiring images and experiencing the thrill of lunar exploration.
In conclusion, May's celestial double feature is a testament to the beauty and wonder of the universe. It offers sky-gazers a unique opportunity to witness two full moons, each with its own cultural and scientific significance. Whether you're an astronomy enthusiast or simply someone who appreciates the natural world, May's full moons are a sight not to be missed. So, grab your telescope or simply look up at the night sky and marvel at the beauty of the Flower Moon and the Blue Moon. After all, as Petro reminds us, 'It’s going to rise right around sunset, so just have a little bit of patience and you’ll be treated to the spectacular view.'
