This is pretty neat. I don't know what they are, but if I had to guess, I would say its possibly chunks of some form of ice. Could it be possible that water is freezing into chunks of ice as it and other matter are hurled from the geysers of Enceladus? Could that matter then somehow be directed towards Saturn's rings? And maybe it's gravity attracting such material? My next thought would be mini meteors or asteroids. Either way it's pretty cool to have pictures of it.
