SkySafari for Android comes in three versions. This is basic version of SkySafari. It shows you 46,000 stars, plus 220 of the best-known star clusters, nebulae, and galaxies in the sky. It displays the Solar System's major planets and moons using NASA spacecraft imagery, and includes the best-known asteroids and comets.
Make sure you have at least 120 MB of free space on your SD card for SkySafari to download this database from our server the first time it runs! (See troubleshooting tips below if you have problems with the download.)
SkySafari accurately shows you the sky from any place on Earth, at any time up to one hundred years in the past or future. It includes encyclopedic descriptions of the constellations, stars, and planets written by professional astronomers. And it contains hundreds of images from NASA space missions, the Hubble Space Telescope, and the world's foremost astro-photographers.
If you have an Android device with a compass, SkySafari can help you identify stars and planets by holding your phone next to them. Tap the Compass button (or tilt your phone up toward the stars) to activate the compass. Now, as you move the phone around, the sky chart follows your motion. Search for any object in the sky, and follow the arrow on screen to find it!
SkySafari has a "Night" button to preserve your dark adaptation 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 compresses days, months, and years into a few seconds.
And all this is just in the basic version! Don't be afraid to start small - you'll end with the universe at your fingertips! SkySafari's streamlined user interface puts both power and simplicity into your hands - and turns your iPhone, iPad, or iPod Touch into an invaluable tool for exploring the night sky. SkySafari is more than just a star chart - it's a celestial travel guide!
Why pay for SkySafari when Google SkyMap is free?
For starters, the basic version of SkySafari includes ten times more star data than Google SkyMap. Our apps contain hundreds of built-in images, and include thousands of object descriptions, written by professional astronomers. Google SkyMap gives you Wikipedia links - which don't do much good out in the field, away from Wi-Fi or data network connections.
Google SkyMap cannot reproduce basic astronomical phenomena like lunar eclipses and Jovian satellite shadow transits. Our apps, by contrast, were developed by passionate astronomers with a penchant for quality and accuracy. We make a living from our products, and we stand by them.
