Last year I discovered a very awesome Advent Calendar, and I re-discovered it over the weekend. I fell in love with it last year, and was so happy to have found it again!
2011 Hubble Space Telescope Advent Calendar
Basically it's photos from the Hubble Telescope, a new one each day, and they are fabulous!! Check it out if you are interested in space at all, I'm sure you'll enjoy it!
