A Whole Bunch of Space and Astronomy Links

Since I haven't had time to write anything lately, instead I'm posting links to a whole lot of interesting articles about space and astronomy from the past month or so, ranging from stories about new discoveries on Mars, the ESA's comet probe, and the NASA probes approaching Pluto and Ceres to ones about extrasolar planet discoveries, speculations about alien life, and one of my favorites, a new idea about sending people to live in a floating city in the atmosphere of Venus, far above the inhospitable surface.
