Look up.
Now you’ll know
what you see.
Stellingo shows the real sky above you — beautifully — and explains it one step at a time, starting with the Sun and the Moon. No telescope, no jargon.
One idea at a time.
Most sky apps throw a thousand labels at you. Stellingo starts with the two things everyone already knows — the Sun and the Moon — and builds from there. Each lens adds one idea to the sky when you’re ready for it.
The Sun
Why it rises, where it peaks, and why its path changes with the seasons.
The Moon
Its phases, why it rises later every night, and where to find it.
The planets
The wanderers: how to tell a planet from a star, and where they travel.
The stars
Constellations, star colours and how far away the light has come from.
The deep sky
Nebulae, star clusters and galaxies millions of light-years away.
Tap the Moon. Then go there.
Everything in your sky opens up: tap the Moon to fly to it, tap a planet to step out into the Solar System, and find out what’s coming to your sky next.
Your sky
The real sky above you, right now, with lenses that explain it.
The Moon
Fly to the Moon: phases, seas, craters and the places we landed.
Sun, Earth & Moon
Why we have day and night, seasons, phases, eclipses and tides.
Solar System
Step outside to see the planets on their orbits, today.
The stars
Fly through the real stars around the Sun, then out to the Milky Way.
ExploreMissions
Ride along with Artemis, Perseverance, Cassini and Parker.
Now stand somewhere else.
The same sky engine, moved to the Moon and Mars. Pick a real landing site or a famous crater, and see its sky: where the Earth and the Sun are, how long the day lasts, what the ground looks like.
MoonThe Earth from the Moon
Stand at Tranquility Base and watch the Earth hang still in a black sky, turning and changing phase.
MoonReal lunar mountains
Every named site is built from NASA's laser maps of the Moon: this is Mount Hadley, above the Apollo 15 landing site.
MoonAn eclipse, from the Moon
When the Moon goes red for us, the Earth hides the Sun for the Moon, and its rim glows with every sunset on Earth.
MarsSunset on Mars
A butterscotch sky, a small Sun, a blue sunset, and two tiny moons racing across the sky.
Don’t miss the good nights.
Full Moons, eclipses, meteor showers and planets at their best — worked out for where you are.
