7 applications to explore the space with the cell phone

Free tools to identify and learn about satellites, constellations, solar system planets and very distant galaxies

Aiming the cell phone to the sky may be enough to see and learn about the stars, planets and even other galaxies. It will not be the same as having the last generation telescope but it is a good option to explore the space.

Here, some applications that can be downloaded at no cost and that allow you to enjoy the universe with that small device that accompanies us everywhere: the phone.

Available for iOS and Android.

3. Space Images

The app was developed by the Jet Propulsion Laboratory, a center responsible for developing unmanned spacecraft for NASA. It has informative images and data about planets, moons, galaxies and more. The photos can be downloaded to the device.
