🌕🪐 A rare Blue Moon is happening tonight — and so is a lineup of five planets.
Skywatchers are in for a rare treat this weekend as a spectacular double celestial event unfolds in the night sky.
On May 30-31, 2026, the moon will reach its full phase for the second time in a single calendar month, marking a rare "Blue Moon." Because the lunar cycle lasts 29.5 days, it occasionally aligns to fit two full moons in one month—with the first, the Flower Moon, rising on May 1.
While the moon won't actually turn blue, it is expected to cast a stunning golden-orange hue near the horizon due to Rayleigh scattering. Adding to the spectacle, observers will also be able to spot a rare planetary lineup, with Mercury, Jupiter, Venus, Saturn, and Mars all becoming visible within hours of each other.
The alignment of five planets alongside a Blue Moon makes this weekend one of the most unusual and highly anticipated skywatching events of the year. For the best viewing experience, experts recommend finding a clear, unobstructed view of the southeastern horizon shortly after sunset on Saturday evening.
While some planets will appear in the dusk sky, others will rise closer to dawn, offering a shifting display throughout the night. If you miss this weekend's lunar phenomenon, you'll have to wait a while: the next monthly Blue Moon won't occur again until December 31, 2028.
Are you planning to watch? What's the coolest thing you've ever seen in the night sky?
