These are pics of Daphnis, a moon of Saturn which orbits between a gap in the gas giant's (heh heh) "A" ring (heh heh heh). The tiny moon's gravity (Daphnis = 8 km in diameter) caused this jiggle in the "A" ring (ha ha) which was captured by the orbiting Cassini probe (do I get a juvenile giggle for probe?).
Scientists have no way of knowing whether I'll make any further attempts at humor today, but rest assured they're working around the clock to prevent another disaster like this post.
