Eclipse: Solar & Lunar

See the sky's greatest events — every solar and lunar eclipse, 5,000 years in either direction — and plan exactly where to watch the next one. Eclipse puts the cosmos in your hand. Spin a photographic globe made from NASA's own pictures, watch the Moon's shadow race across Earth, and find out what the next eclipse will look like from your own backyard — or where to go to stand in totality. Whether you're a curious first-timer or a lifelong eclipse chaser, Eclipse meets you where you are. Watch it happen - Spin a photographic globe, with city lights on the night side and the Moon's shadow passing over - Scrub through time and watch the shadow sweep across the world - Pinch to zoom from space down to satellite maps with roads and towns Plan from your spot - Tap anywhere — or use your GPS — to set your place - Every eclipse in the list tells you what you'll see from there: total and for how long, how much of the Sun is covered, or not seen at all - Precise local times for when it begins, peaks and ends, and how high the Sun stands - Outside the path? See how far totality is, which way, and a town inside it you can switch to with one tap - A heads-up when you're close to the edge of the path, or when the Sun is low and you'll need a clear horizon - Add the eclipse to your calendar, with every contact time Solar and lunar, side by side Pick any eclipse from one chooser, solar or lunar: - Solar: the sky darkening as the Sun is covered, the corona at totality, and the "ring of fire" of an annular eclipse - Lunar: the real Moon turning deep copper in Earth's shadow — the "blood moon" — on a star chart with named stars and constellations Learn as you go - Simple, beautiful guides: what causes eclipses, total vs. partial vs. annular, and the science behind the blood moon - How to watch safely — certified eclipse glasses, pinhole projection, and the methods that actually work - The myths and stories cultures have told about eclipses — and what's really going on - A guided tour walks you through everything on first launch Browse a 5,000-year catalog - Nearly 12,000 solar and 12,000 lunar eclipses, from 2000 BCE to 3000 CE - Search for a year or a Saros series, filter by type or period, or show only the ones visible from where you are - Built on NASA / Fred Espenak eclipse predictions — the same data the experts use Share any view Found a spectacular one? Send a link that opens the exact same globe, date, and location on your friend's phone. Going deeper — for the eclipse-obsessed Everything above is all most people will ever need. But if you like to look under the hood, it's all here: - The Saros cycle — play a whole Saros family and watch its eclipses march across the centuries - The Saros–Inex Panorama — every eclipse in history on one zoomable, colour-coded grid - The Syzygy Explorer — a lattice of every new and full Moon, where the great orbital rhythms line up before your eyes - Full technical readouts — Besselian elements, gamma, magnitude, delta-T, path width and sub-solar point; and for lunar eclipses, sidereal positions with Nakshatra & Ayanamsha Free, with no ads and no accounts.
