SkySafari 4 Pro – The Most Revolutionary Stargazing App


August 2015 – Recently updated for both Android and iOS, SkySafari 4 Pro is the ground- breaking astronomy app that places the entire universe in your hands.

Created and developed by the space-obsessed Simulation Curriculum, SkySafari 4 Pro boasts the largest database of any astronomy app available for iOS and Android devices and features a mind-blowing 1.2GB of data. Featuring information on 25 million stars from both Hubble Guide Star catalogues, over 740,000 galaxies down to 18th magnitude, more than 630,000 solar system objects and every comet and asteroid ever discovered, SkySafari 4 Pro truly is a fully comprehensive planetarium at your fingertips.

As the latest app in mobile stargazing technology, the innovative SkySafari 4 Pro simulates the view from anywhere in the solar system up to a staggering one million years in the past or future. As the ultimate astronomer’s companion, the app includes NASA’s latest Moon and Mars maps with 8 times the resolution of any previous SkySafari iteration.

SkySafari 4 Pro’s astronomical encyclopedia is packed with over 1,500 detailed descriptions of the constellations, stars and planets written by professional astronomers. What’s more, with 800 high-definition images from NASA space missions, the Hubble Telescope and the most renowned space photographers in the world, the revolutionary app will transform your astronomy experience and replace the clunky, expensive computer software of yesteryear. Excited about the recent update, app developers Simulation Curriculum said: “SkySafari 4 Pro is the world's most powerful astronomy app, period. It has the biggest database, the most advanced simulation, and most capable telescope control, hands down.”

SkySafari 4 Pro is available to download via the Google Play Store and Apple iTunes Store for Android and iOS devices respectively, and is fantastically priced at $39.99. For those who aren’t quite ready to make this giant leap into the cosmos, two lower-priced introductory versions are available. SkySafari 4 Plus ($14.99) and SkySafari 4 ($2.99) are also available now on the ITunes Store and Google Play.

Notes to Editors - SkySafari 4 Pro has been created by Simulation Curriculum.
