Speaking of Hubble, If you're looking for a holiday card that isn't all twee and treacly and gooey, then the good folks at Hubble have just what you need: astronomical holiday cards!
They have a nice selection of cards, and they're all free! Just download them and print them at home or at a print shop. Why give someone the usual kids-on-a-sled card, when you can have a whole galaxy on it?
