New Delhi: Skywatchers and astronomy enthusiasts are set to witness a rare celestial phenomenon on May 31, 2026, when a ‘Blue Moon’ will illuminate the night sky on the occasion of Jyeshtha Purnima. The event has generated excitement among people across the world due to its rarity and visual appeal.
Contrary to its name, the Moon will not actually appear blue in colour. The term ‘Blue Moon’ is traditionally used for the second full moon occurring within a single calendar month or, in some cases, the third full moon in an astronomical season containing four full moons.
According to astronomers, this rare lunar event does not occur frequently, which is why the phrase “once in a blue moon” is often used to describe something uncommon. Experts say the Moon may appear brighter and more radiant than usual under clear atmospheric conditions.
The full moon of May 31 also coincides with Jyeshtha Purnima, an important occasion in the Hindu calendar observed with religious rituals and fasting in many parts of India.
Astronomy lovers are expected to gather in open areas to witness the spectacular sight. Experts advise viewers to observe the Moon after sunset for the best experience, especially from locations with minimal light pollution.
The rare alignment of a culturally significant full moon and an astronomical phenomenon is expected to make the night of May 31 memorable for both devotees and skywatchers alike.
