This is a good one. It now seems you can so anything with computer simulation. At http://phys.org/print389947158.html … modelling has shown Venus could have been habitable, 715 million years ago.
At http://phys.org/print389972002.html … Curiosity Rover has descredited the consensus view Mars had a mainly basaltic rocky crust. Geological studies by the robotic machine have turned that idea upside down – but why would they assume Mars was inactive? John Bridges from Leicester University has provided information on what Curiosity Rover has achieved in the last couple of years – and what future areas of interest it will explore. It has come across ancient lake beds and a silica rich crust seems to be the order of the day – amongst other discoveries.
