The Star Walk and NASA apps are two excellent sources that can take you to the final frontier!

The app enables you to point your device at the sky, day or night, and find out what stars, constellations, planets and satellites are in that location in real time. Touch an object to zoom in and get more information. Very cool!The NASA app collects an extensive selection of news, images and video from various online NASA sources. You can get NASA mission info, live streaming of NASA TV, NASAimages.org and NASA video all at your fingertips.
