Saturn's Newest Moon
Surprise! Astronomers analyzing images taken by NASA's Cassini spacecraft have found that Saturn has yet another moon in one of its outermost rings:
A faint pinprick of light embedded in one of Saturn's outermost rings is now the 61st moon known to be circling the giant planet, astronomers announced today. [...]
Based on its brightness, astronomers estimate that the as-yet-unnamed moon is a third of a mile (half a kilometer) wide. This is tiny as far as moons go, but the object is likely the largest in its neighborhood.
