There's nothing quite as mind blowing as a photo of a black hole imploding, a star being born or a solar flare. This app works with Nasa's recently launched Space Images website to send you the latest pictures from the solar system.
If you're on the hunt for alien beings, this app will help keep you informed of all extra-terrestrial happenings. The interactive map charts every UFO sighting in the world, with hundreds of pictures and videos of UFOs.
It comes at a price, but Mobile Observatory really is one of the most comprehensive astronomy apps available. As well as a zoomable sky map, the app features an interactive top-down view of the solar system, a calendar of celestial events and detailed catalogues of thousands of spatial goings on.
A staple for space cowboys, the Nasa app will keep you in the know about everything from missions, news, and countdown clocks for launches. It's the best way possible to stay up to date with the world's space association.

Not an app as such, but a free mobile service, Spot the Station gives you free text or email notifications whenever the International Space Station is visible. Bright enough to be seen even from a city, you'll always know when to look up.

The perfect way to learn the night sky, simply hold your phone up and an annotated star map on your screen will display the view of the bit of sky you are looking at, naming constellations, planets and more. Trick your friends by saying it uses your phone's camera, but really it works with the built-in compass to establish the direction you're facing.
Control the entire universe (kind of), with this app that simulates the physics of interacting galaxies as well as computing the gravitational forces between stars. You can change the parameters of the simulation, testing out and visualising the infinite different interactions of galaxies.
