Slovakia to witness rare 'Blue Moon' phenomenon at end of May
Share:
Slovakia will experience a rare astronomical event on May 31 when a 'Blue Moon' appears in the sky. The phenomenon occurs when two full moons happen within the same calendar month, making the second full moon the so-called Blue Moon. Despite its name, the moon will not actually appear blue in color but represents an uncommon celestial occurrence that happens roughly every two to three years.
