For decades now, Europa has beckoned – this moon of Jupiter which is frozen on the outside but hides a global ocean on the inside – has so far only been visited by spacecraft during brief flybys. Scientists and the […]

A Martian Paradox: Curiosity Rover Findings Raise New Questions About Water on Ancient Mars

View from Curiosity of the Yellowknife Bay rock formation. Drilled samples here and elsewhere provided evidence that this region used to be at the bottom of a lake, but also that there are little or no carbonate mineral deposits, which should have been produced if the carbon dioxide atmosphere was thicker and warmer billions […]
