Those pics are terrific - thanks for posting. I love the animation of the moon capturing the sun's rays through the rings.
Can anyone explain why some moons (like ours) are pretty much perfectly spherical, whereas others (like some of Saturn's moons) are more like oddly shaped lumps of rock that have drifted into planetary orbit? They seem to have avoided the 'shaping' process somehow. Any thoughts anyone?
PS: If it's not ok to ask this question here, feel free to move it
Cheers
