What's Up for the BlackBerry PlayBook gives you all the stars in the sky, and more!

Anyone who is in to astronomy will appreciate this well done application for the BlackBerry PlayBook. What's Up shows real-time positions for the sun and moon, major planets, and 5000 of the brightest stars in the sky. Set your current position by GPS or zip code, search for constellations, stars, planets and more even if you're not sure of the exact name, and view them all on the star chart. The basic functions of What's Up don't even need an internet connection, which makes the app perfect for stargazing at night when you're away from the city lights, especially when you consider how portable the BlackBerry PlayBook is!

Additional features include:

• GPS support for setting geographic coordinates
• Advanced text search including phonetic search
• Multitouch gesture support for zooming and panning
• Innovative "Quick Links" providing seamless integration with Wikipedia articles

You can grab a free trial of What's Up that will give you full functionality for 5 days, after which pinch-to-zoom and search will be disabled. The full version is just $.99 and definitely worth it if you ever look up in the sky and wonder what it is you're looking at. My kids especially love it, and I think it's an awesome tool for teaching them about all those mysterious twinkles in the sky. Download or purchase What's Up from the links below, and check out a few extra screenshots after the break. (Unfortunately, the screenshots don't really do the app justice due to the reduced size.)
