SpaceTerra: Universe & Earth

SpaceTerra brings the universe and our planet together in one free app. Step outside and find out what is above you, then see what is happening on Earth right now.

UNIVERSE
- Picture of the day: a new astronomy picture every day, the full archive back to 1995, "On this day" and an optional daily wallpaper
- Sky tonight: the Moon, the visible planets, darkness times and a clear-night score from the local cloud forecast
- Sky map with AR: point your phone at the sky to name stars, planets, constellations and deep-sky objects, with a red night mode
- ISS: live position, passes over your place, reminders and who is in space right now
- Sky events: eclipses, meteor showers, Moon phases and oppositions, with reminders
- Observing log: Messier and Caldwell checklists, and the best targets for tonight
- Milky Way planner, bright comets, Webb's observing schedule, Deep Space Network live, exoplanets and Mars rover photos

EARTH
- Earth today: whole-Earth photos from deep space
- Live Earth events: wildfires, storms, volcanoes and earthquakes on a map, with an optional strong-quake alert
- Satellite map of the planet, updated daily
- Aurora forecast, space weather and asteroids passing Earth

AND MORE
- Upcoming and past launches, with countdowns and reminders
- Space news, videos and podcasts
- A daily quiz with streaks and badges
- Home screen widgets, favourites for everything and a Today screen you arrange yourself
- Light and dark themes, metric or imperial units, and 15 languages

What you have already seen is kept on your phone, so screens open quickly and stay readable without a connection. The sky map, the sky calculations, the Moon map and the quiz work offline. Your place stays on your device: the app sends only a rounded position to the weather service for the stargazing forecast.

SpaceTerra is free, with banner ads on some screens.
