See the best photos of May 2025's full Flower Moon as it rose over landmarks and landscapes worldwide in a dazzling lunar display.

According to NASA, an Old English name for the May full moon is the milk moon. In 703 AD, the English monk St. Bede the Venerable wrote that May was known as the "Three-Milkings Month," likely because cows could be milked three times a day during this fertile time of year.

With springtime weather in full effect, it’s no surprise that the full flower moon will illuminate the sky May 12.

May's full moon, known as the Flower Moon, will bloom in the sky in all its glory on May 12, so catch it if you can.

The Algonquin tribes of what is now the northeastern United States called May's full moon "the flower moon due to the abundant flowers that bloom this time of year," according to the Almanac. Other nicknames for the full moon include the "corn moon" or "corn planting moon."

It's May, which means Spring has sprung and rebirth is everywhere. Astrologically, all that regeneration has huge significance, and it all culminates with the May 12 Flower Moon in Scorpio, which is all about rebirth, rejuvenation, and fruition.

The moon will slide in front of the red supergiant star Antares on May 13, briefly blocking its light just a day after reaching its full "Flower Moon" phase.
