Interactive 3D atlas of the cosmos
Fly from galaxies
down to single moons
CosmoLapse is a cinematic, browser-based atlas of the universe. Cross every scale, from the Local Group of galaxies into the Milky Way, the Solar System, and on to real exoplanet systems, planets, rings, and moons.
No account. No trackers. Works in your browser.
- Real-time planetariumEvery star, orbit, and position updates live.

A real-time planetarium that lives in a browser tab
CosmoLapse turns public astronomical data into a navigable, cinematic universe. Pick any body and a detail panel opens with figures, a live summary, and travel-time analogies from Earth.
Built to explore, grounded in real data
Galaxy to planet
Glide from the Local Group of galaxies into the Milky Way, the Solar System, and individual planets and moons.
- Smooth flight across scalesNo loading between worlds. Just fly.
- Real exoplanet systemsExplore confirmed worlds around other stars.
- Honest scale modesCinematic, relative size, and true distance.
Start your way
Pick a mode and launch straight in
Each mode opens the atlas already set up for a different kind of exploration, from a guided tour to a data-rich science view.
- LiveSolar System nowSee the planets exactly where they are right now, every world placed at its true position for this very hour.
- GuidedCinematic tourSit back as the atlas flies itself from the Local Group down to the planets, narrating each stop.
- Free flightSolar SystemOpen straight onto Earth and the Sun, free to click any world and fly to it.
- DataScience modeTrue relative sizes, measurement overlays, constellations, and probe trajectories, all switched on.
- ExoplanetsHabitable worldsJump into TRAPPIST-1, seven Earth-sized planets around one ember of a star.
- Widest viewCosmic scaleBegin at the Local Group of galaxies and work your way inward, one scale at a time.
- SpacecraftDeep-space probesStart in the Solar System with the Voyager, Pioneer, and New Horizons trajectories lit up and clickable.
- SizePlanet Size ScaleStep from a soccer ball up to Earth, the planets, and giant exoplanets, one size at a time.
The sky right now
See every planet at its true position for this very hour, scrub time to any date, and read the Moon's real phase and the evening sky.
Travel from Earth
See how far each world is and how long the trip would take by car, by airliner, by spacecraft, and at the speed of light.
Walk the surface
Step onto Mars and the Moon and look around real NASA 360 panoramas in first person, from Curiosity, Perseverance, Opportunity, Spirit, and Apollo.
Real exoplanet systems
Step into TRAPPIST-1, Proxima Centauri, Kepler-90, and 51 Pegasi and explore their planets like our own.
Compare worlds
Put up to three bodies side by side across size, mass, gravity, day length, and temperature, with rotating 3D previews.
Honest scales
Three ways to see the Solar System
Sizes and distances cannot be true to scale at once, so CosmoLapse lets you choose, and always tells you which view you are in.
- 01CinematicA balanced, beautiful layout tuned for exploring and storytelling.
- 02Relative sizeTrue relative diameters, so you can feel how vast the giants really are.
- 03True distanceReal orbital spacing, where planets become distant, lonely specks.
Cinematic tour and scales
A guided fly-through plus cinematic, relative-size, and true-distance modes, always labelling which scale is in use.
Shareable and bilingual
Every view has its own link, the interface is in English and Polish, and accessibility options are built in.
How it works
