Life-sustaining planets in interstellar space?
Article Abstract:
Rock and ice embryos of the order of Earth's mass can be formed during planet formation, some of which may be ejected from the Solar System. Such bodies retain atmospheres rich in molecular hydrogen. Many models of planet formation involve the accumulation of solid bodies. It is possible that there are bodies with water oceans in interstellar space which are expected to have volcanism in the rocky parts.

A new spin on Saturn
Article Abstract:
Data from the Cassini mission, presently investigating the Saturn system, observes a signal in Saturn's magnetic field of period about 10 hours47 minutes, which might be the planet's true rotation period. This shows that Saturn is spinning more slowly than thought before and it would affect the estimates of the size of its likely inner core of rock and ice.

Volcanoes on Quaoar?
Article Abstract:
The study proposes the dynamical implication of the formation of Quaoar, the largest known body that has crystalline water ice on its surface. The presence of crystalline ice is surprising, because it is widely believed that its formation requires a temperature of around 100 K or more substantially higher than the surface temperature of the bodies.
