peek-a-boo Jupiter

This happened on Christmas Day, but I've only just come across it.

Rafael Defavari took a video of the moon occulting Jupiter.  It's marvellous, and made even more so by what you can see as Jupiter re-emerges from behind our moon:

Lunar occultation of Jupiter - 25 December 2012
The little dot just visible above-left of Jupiter is one of its moons: Europa.  And the darker dot on Jupiter itself is Europa's shadow!  (It's easier to see on the video.)

There's more info where I found out about this, at Phil Plait's Bad Astronomy site.
