New observations from telescopes in South America of asteroid (10199) Chariklo, as it passed in front of a distant star, have revealed rings. Astronomers believe the rings may be partially composed of water ice.

The newfound object, called 2012 VP113, joins the dwarf planet Sedna as a resident of a far-flung region called the "inner Oort Cloud." Further, 2012 VP113 and Sedna may have been pulled into their odd orbits by a big, undiscovered planet.

Chariklo is the first asteroid discovered to have it's own ring system, and only the fifth body in the solar system. The largest of a class of asteroids known as Centaurs that orbit between Uranus and Saturn, Charriklo has two distinct, narrow rings.

Astronomers have now discovered two dwarf planets — Sedna and 2012 VP113 — in the distant inner Oort Cloud, a largely unexplored region that likely hosts millions of icy objects.

A distant spiral galaxy is leaving behind much of its gas as it shoves its way through its parent galactic cluster. The result will be fatal, as the galaxy will lose most of the fuel it requires for star formation.

Curiosity is just 282 feet north of a site called "the Kimberley," where four different types of terrain intersect. The rover's handlers are keen to study the Kimberley rocks and may even break out Curiosity's sample-collecting drill at the site.
