Speaking of rings (yesterdays post) the same subject is uncannily the feature of an article today at Universe Today (see http://phys.org/print391077112.html ). It is an interview with Kevn Gill who does computer enhancement imaging. His latest work is on Daphnis, a moon of Saturn, embedded in one of the rings. In the past he has made models of Earth with a ring system and what Mars might have looked like if it had vegetation and surface water.

At http://phys.org/print391070737.html … astronomers have discovered a hyper inflated Jupiter like planet. This makes the current Jupiter mission of more interest at another angle in that we might get to know if Jupiter itself has inflated and how that might happen. Is it the atmosphere (gases) that expands or the planet itself (assuming there is something underneath the gas). Will it shed light on the process of expansion and cane rocky planets also expand?

At http://phys.org/print391076508.html … Curiosity Rover has sent back images from Mars of the topography that are reminiscent of mesas and buttes in the US Southwest.
