On Pluto, a slurry of nitrogen and water ice melted by subsurface heat stands in for lava, the team suggests, freezing solid once it is exposed at the surface.

«More nitrogen has to come from somewhere to resupply both the nitrogen ice that is moving around Pluto's surface in seasonal cycles, and the nitrogen that is escaping off the top of the atmosphere as the result of heating by ultraviolet light from the Sun,» said Singer.

Instead, they appear bright white, more like the regions of Pluto covered in nitrogen ice, according to work presented at an American Astronomical Society meeting on 17 October by Will Grundy at the Lowell Observatory and Orkan M. Umurhan at the SETI Institute.

«This is probably because water ice is hidden by volatile materials like methane, nitrogen and carbon monoxide.»

The paper, «Reconstruction of past atmospheric CO2 concentrations by ice core analysis», acknowledges that, due to impurities, liquid water can exist as low as -50 deg C.
