Advent of astronomy

If you like astronomy pictures, but hate getting too many at once, then may I suggest a few astronomical advent calendars?
The (fantabulous) Big Picture is once again doing its Hubble Advent Calendar, featuring one amazing Hubble image every day until Christmas.
Speaking of which, the Hubble people have printable holiday cards featuring images on them, and they’re free!
And if you prefer your advents closer to home, Emily at The Planetary Society blog is doing one as well with solar system objects. Bonus: hers runs through January 1st! I’ve included a small version of her first pick here. Know what it is? Go to Emily’s page and find out!
Finally, the good folks at Zooniverse have a fun advent calendar that’s interactive; roll over the window to reveal the picture. Try to look at a future one and it just gives you a question mark! So no peeking.
I like this idea: it’s good way to promote astronomy and science, and makes people come back for more!
