Mobile Observatory - Astronomy

Mobile Observatory is one of the most complete astronomy apps available for Android devices and the perfect tool for anybody interested in the sky's wonders, from the occasional sky gazer to the passionate amateur astronomer.

You want to know if the next lunar eclipse is visible from your location or when the next bright comet is visible? You would like to be notified by your smart phone the next time, Jupiter and the Moon meet in the sky? You want to know what the blazing bright object in the evening sky is? You want to be always up-to-date which celestial events are visible from your location? Then this app is a must-have for you!

The app does not only include a live, zoomable sky map telling you what sky object you are looking at but provides you with loads of detailed extra information on stars, planets, deep sky objects, meteor showers, comets, asteroids, lunar and solar eclipses as well as detailed ephemeris of all included sky objects and an interactive top-down view of the Solar System. All that in just one app!

Presently, Mobile Observatory is available in three different languages: English, German, and Spanish. Localisation to further languages is in progress.
