The Observable Universe
A journey across space & time — an interactive 3-D atlas of the cosmos, from the Moon to the relic light at the edge of everything we can see.
Explore in 3-D
Drag to orbit, pinch to zoom, and tap any object to inspect it up close — rendered from real NASA & ESO imagery.
Look Back in Time
Every object reveals how far back in time you’re seeing it — the Sun 8 minutes ago, the cosmic dawn 13.8 billion years ago.
A Living Solar System
Planets orbit on real elliptical paths, with moons, asteroid and Kuiper belts, and comets streaming twin tails.
Live from NASA
The nearest confirmed exoplanets stream in live from the NASA Exoplanet Archive, in their true positions in the sky.
Launch from Earth
Choose a destination and ride a spacecraft there on a real gravity-turn launch — lift off, accelerate, cruise, arrive.
