SkySafari Lite is a celestial travel guide. It's an easy-to-use planetarium program app to help you explore the night sky. It is brought to you by Southern Stars, previously the mobile application division of Carina Software.

SkySafari Lite is the intro version of SkySafari, our professional iPhone astronomy software. SkySafari Lite shows you nearly 120,000 stars, plus 220 of the best-known star clusters, nebulae, and galaxies in the sky. It displays all the major planets and moons of the Solar System using NASA spacecraft imagery, and includes a database of several dozen asteroids, comets, and artificial satellites.

SkySafari Lite accurately shows you the sky from any place on Earth, at any time up to 100 years in the past or future. SkySafari Lite also includes informative descriptions of the constellations, stars, and planets. It contains hundreds of images from NASA space missions, the Hubble Space Telescope, and from the world's foremost astro-photographers.

If you have an iPhone or iPad with a compass, SkySafari Lite can show you the sky in same the direction that you're holding your phone. Shake the phone to activate its compass and accelerometer - now you can identify stars and planets by holding your phone next to them. You can find any object in the sky by following an arrow that points in its direction.

SkySafari Lite contains interface themes let you change the look-and-feel of the app. In addition to the
"Classic" look, there's now a cool black "Onyx" theme, and a "Night Vision" theme that preserves your dark adaption as you're exploring the night sky.

The Time Flow feature lets you animate the night sky using simple VCR controls. Follow the motion of the stars and planets as SkySafari Lite compresses days, months, and years into a few seconds.

SkySafari Lite's simple user interface makes it an invaluable tool for exploring the night sky.

For advanced users, the full version of SkySafari contains a much larger database of 2.5 million stars and 31,900 deep sky objects. If you have a computer-controlled GoTo telescope, SkySafari can use your iPhone or iPod's built-in WiFi to point your telescope in the sky.
