Just to geek out even more-- I really liked this one of enceladus too [0] ... I wish I knew an astronomer who could explain what that 'shooting star' looking thing is in that pic..
Do you have any ideas?
I'd expect every bit of light to be streaked if it was a long exposure, so it has to be something moving? Massive "I'm totally uneducated on all this stuff" disclaimer -- but if this pic was taken from inside saturn's atmosphere; did it capture a 'shooting star' ??
It's probably a cosmic ray, which overloads the CCD detector in a streak-like pattern as it flies through the focal plane. All uncorrected deep space imagery has them.
