Eclipse: Solar & Lunar Sky

Every solar and lunar eclipse for 5,000 years, on a globe you can spin. Contact times for your exact spot. No ads, no accounts, no network needed.

See the sky's greatest events — every solar and lunar eclipse, 5,000 years in either direction.

Eclipse turns the machinery of the cosmos into something you can hold in your hand. Spin a globe, watch the Moon's shadow race across Earth, and find out exactly what the next eclipse will look like from your own backyard.

Whether you're a curious first-timer or a lifelong eclipse chaser, Eclipse meets you where you are.

Watch it happen

• Drag to spin a 3D globe, and pinch to zoom from space right down to street level
• Watch the shadow sweep across the world as you scrub through time
• Zoom in and the globe hands off to a detailed map, with a day/night line showing exactly where the eclipse is visible

See it from your location

• Tap anywhere — or use your GPS — to drop your spot on Earth
• Get precise local times: when the eclipse begins, peaks, and ends
• See how much of the Sun will be covered, how high it sits in your sky, and whether you'll catch totality

Two eclipses, one app Flip a single switch between Solar and Lunar:

• Solar: follow the path of totality and the "ring of fire" of an annular eclipse
• Lunar: watch the Moon glide into Earth's shadow and turn deep copper-red — the "blood moon" — on a realistic 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
• Filter by type, by year, or by "visible from where I am"
• Built on NASA / Fred Espenak eclipse predictions — the same data the experts use

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, ΔT, path width and sub-solar point; and for lunar eclipses, sidereal positions with Nakshatra & Ayanāṁśa
