Real-time 3D · Runs offline

Explore Earth, time, and the whole solar system.

ATLAS is a living 3D map of our world and the cosmos. Read any city's exact local time, then fly out past the real-positioned planets, moons and stars — and travel through time to watch it all move. All in your browser.

What you can do
One window onto everything.

From the time in your city to the rings of Saturn — ATLAS brings the planet and the cosmos into a single, fluid 3D space.

🌍

Live Earth & timezones

Click or search any city for its exact local time, AM/PM clock, UTC offset and real day/night — backed by a full timezone database.

🪐

The real solar system

Every planet, Pluto, major moons, the Sun and the ISS — placed at today's true positions using NASA orbital math.

A time machine

Scrub to any date and watch the planets orbit and Earth's day/night line sweep across the globe.

The real night sky

Named stars, galaxies and nebulae at their true sky coordinates — with constellations you can switch on.

🚀

Fly anywhere

Point at anything and zoom — drift from a city street to Neptune with no limits and no clicking around.

📡

Built for every screen

Capture any moment in space-time. Share it as a link.

No other space explorer fuses a live world clock, a true-to-date solar system and a real star map into a single offline file.

Pick a city, travel to a date, frame the cosmos — then hit Share. ATLAS copies a “Postcard” link that reopens the exact same instant for whoever you send it to. That's something you simply can't do anywhere else.

Good to know
Questions, answered.
Do I need to install anything? +
No. ATLAS runs entirely in your web browser — just open it. There's no app store, no download, and no account.
Does it work offline? +
Yes — the Earth, planets, stars, the time machine and timezones all work with no connection. Only the worldwide city search, auto place-names and live ISS tracking need the internet.
Is it accurate? +
Planet positions are computed from NASA's orbital elements for the exact date you choose, and timezones come from a complete database — they're DST-correct. Distances are shown compressed for visibility, with a true-scale mode you can switch on.
What devices does it support? +
Phones, tablets, laptops and desktops. It automatically renders lighter on mobile and adapts the layout to every screen size.
How much does it cost? +
It's free. ATLAS is a single self-contained file with no ads and no tracking.
