New Ring Discovered around Saturn

It’s amazing how much we still don’t know about our solar system:

New ring discovered around Saturn

“The Cassini spacecraft has identified a faint, previously unknown ring circling the giant planet Saturn. It appears to be composed of material blasted off the surface of two saturnian moons by meteoroid impacts. The moons Janus and Epimetheus may be too small to hold on to dust kicked out by these impacts, so it escapes into space, spreading out into a ring. The tenuous, wispy ring coincides with the orbits of these two moons, mission scientists noted.”
