Square ice between two graphene sheets as seen in a transmission electron microscope (TEM); high-contrast dark spots are oxygen atoms that indicate positions of water molecules; hydrogen atoms yield too little contrast to be resolved even by the TEM. The top right inset shows a magnified image of a small area in the centre of the ice crystal. Image credit: University of Ulm.

This graph displays the different values of the deuterium/ hydrogen ratio in water observed in various objects in the Solar System: the data points are grouped by color as planets and moons (blue), chondritic meteorites from the asteroid belt (grey), comets originating from the Oort cloud (purple) and Jupiter family comets (pink). Rosetta’s Jupiter-family comet is highlighted in yellow. Diamonds represent data obtained in situ; circles represent data obtained by astronomical methods.

Water-carved valley on Mars. The researchers have found that some of these valleys appear to have been formed by orographic precipitation - rain or snow that falls when moist air is pushed upward by mountain ridges or raised crater rims. The findings suggest that at least some of the water on ancient Mars fell from the atmosphere, rather than bubbling up from the subsurface (NASA)
