The response has been absolutely amazing since we began our regular series of giveaways two months ago. As a way of showing our gratitude -- not to mention the fact that these contests aren't going away anytime soon -- we're offering up three new iPads over the next three days! That's right, you'll have the chance to win one of Apple's latest tablets each day through Friday.

Let's meet our first contestant. We have a 16GB WiFi-only iPad up for grabs, courtesy of HarperCollins and its new app called "Wonders of the Universe." The astronomy app was designed for iOS5 and takes full advantage of the new iPad's Retina display. It essentially combines seven programs into one, offering a visual experience that lets you explore the Universe from subatomic levels all the way up to full galaxies. So read the rules, leave a comment and you've successfully entered to win for the first day! But you'll need to come back tomorrow and Friday if you want to take a shot at the other two.
