The folks at Hubble just released this fantastic image!
OK, duh, that's Saturn. But you can see four moons crossing its face at the same time! Such an event is pretty rare, and very cool. The moons are (from left to right) Enceladus, Dione, Titan, and Mimas. You can also see the shadows of Enceladus and Dione on the planet's cloudtops, too. Whoa.
Saturn, like the Earth, is tilted with respect to its orbit around the Sun. Our tilt is about 24 degrees, and Saturn's is about 27. This means that twice every Saturn year (which are roughly 30 Earth years in length) we see Saturn's rings edge-on. They can get so thin they practically disappear! That happens in September of this year, and as you can see from the image above image, our viewing angle of the rings is currently very shallow. The icy particles in the rings orbits ...
