Blue Moon May 2026: Viral Claim Says It Will Be the Largest and Most Dangerous in 500 Years—Here’s What Scientists Say
A viral post circulating on social media claims that the Blue Moon in May 2026 will be the largest and most dangerous lunar event in 500 years, with predictions of extreme tides, earthquakes, and even volcanic eruptions.
This claim is fake. While a Blue Moon—defined as the third full moon in a season with four full moons, or a second full moon in a calendar month—is set to occur in May 2026, astronomers confirm it will not be super-sized or hazardous. The term "Blue Moon" refers to a calendar oddity, not a color or size. The moon will look slightly brighter and larger only if it also coincides with a perigee (closest approach to Earth), which is not predicted for May 2026. No credible scientific evidence links lunar phases to catastrophic events. The viral claim likely exaggerates a rare occurrence to fuel fear and engagement. Check sources like NASA or the Adler Planetarium for accurate lunar updates.
