Blue moon may 2026: 5 mind-blowing facts about May's rare supermoon you can't miss
- A blue moon may 2026 is actually not blue in color—it refers to the second full moon in a single calendar month. May 2026 will host two full moons: the first on May 1st and the second, the "blue moon," on May 31st.
- This blue moon will also be a supermoon—meaning it will appear up to 14% larger and 30% brighter than a typical full moon due to its closest approach to Earth. May 31st's moon will be 2026's most dazzling lunar display.
- The last time a blue moon and supermoon coincided in May was in 2021, and it won't happen again until 2028. You're catching a celestial rarity that will be the talk of every skywatching community.
- To catch the best view, look east just after sunset on May 31, 2026. No telescope needed—just clear skies. NASA recommends finding a spot away from city lights for the brightest, most vivid experience.
- This event will saturate social media with viral photos, time-lapses, and hashtags like #BlueMoonSupermoon. Expect news coverage worldwide, so you'll want to have your camera ready to join the trend.
