Astronomers Predict That Pluto Has a Ring

"Until recently, the only ring in the Solar System was Saturn's. But in 1960s and 70s, astronomers discovered rings around Uranus and Neptune. Meanwhile, the Voyager 1spacecraft sent back images of Jupiter's ring.

To be sure, these rings are much less impressive than Saturn's but the implications are clear: rings seem much more common than astronomers once thought. Perhaps they are even the norm."


"Fortunately, there is a way to settle the matter.

The New Horizons spacecraft is currently on its way to Pluto, equipped not with a camera capable of seeing the ring but with a dust counter that should do the trick instead. If this probe finds itself in the lightest of dust clouds when it arrives on 14 July 2015, we'll finally know for sure.""
