## What is Universe Atlas?

Universe Atlas is an offline, interactive atlas of cosmic structure. Zoom continuously from planets to the observable universe across five scales; open any layer for deep archives, key figures and long-press plate annotations. Build a parameterized galaxy and run the rotation-curve experiment with and without dark matter. Design a nebula and watch its blackbody color respond live. Fly at relativistic speed and read time dilation and length contraction as you push the throttle. Check what is up in your sky tonight — 19 landmarks ranked by visibility for your hemisphere and date — and plan waypoint journeys across distance bands.

Everything runs on device: no account, no ads, no in-app purchases, no network calls. Includes the cosmic timeline (380,000 yr to 13.8 Gyr), a scale-compare playground, observation tasks and star challenges.

Fully localized in 10 languages — English, Simplified Chinese, Traditional Chinese, Japanese, Korean, Spanish, French, German, Brazilian Portuguese and Russian: the app follows your system language by default, and you can switch anytime in Archive → Settings → Language, without a restart.

Note: simulators and visibility rankings are simplified educational models, not research-grade instruments; deep-sky plates are original illustrative artwork, not photographs.
