Total solar eclipse, Perseid meteors, and six-planet parade converge in 48-hour celestial window Aug. 12–13

On August 12–13, 2026, a total solar eclipse crosses Greenland, Iceland, Spain, and Portugal, the Perseid meteor shower peaks under new moon skies, and a six-planet parade aligns — all within 48 hours. NASA expects 50–100 meteors per hour. The overlap of three independent celestial cycles is uncommon, creating a daylight-to-darkness observational sequence few years match.
