MSNBC:

None of us living today will ever get beyond our celestial backyard in real life, but there’s a fleet of apps out there that can blast you through hyperspace to explore — and understand — the far frontiers of the cosmos on your tablet computer. The latest app is “The Wonders of the Universe,” a multimedia spin-off of physicist Brian Cox’s coffee-table book and TV documentary series of the same name.The app, sold by Harper Collins for the iPad 2 and the new iPad, organizes more than 200 interactive articles, two and a half hours of video and hundreds of graphics to do a show-and-tell that ranges from subatomic quarks to the largest scales of the cosmic web.

The article also mentions and has video of four other space-themed apps for the iPad: The Night Sky, Solar System for iPad, Solar Walk and my personal favorite, Star Walk.
