Well, now you can have a say in where Hubble will point next. In conjunction with the International Year of Astronomy 2009, NASA has created a site - You Decide Hubble's Next Discovery - where you can vote for one of six possible targets.
Votes can be cast through March 1st, after which Hubble will image the winning object. It will be released during the IYA 100 hours of Astronomy held April 2nd through 5th. After casting your vote, you can also register to win one of 100 prints of the released image. If you are a teacher or educator, NASA has also developed special classroom activities so your kids can participate in the event.
So get over there now to cast your vote... I have. We'll see who's favorite shows up in April!
