The extreme heat on the planet Mercury likely helps make ice on its polar regions, according to a study which suggests how water could arise, and collect as ice on planets rife with all the necessary components. The researchers from the Georgia Institute of Technology said while asteroids may have delivered most of Mercury's water, the planet's extreme daytime heat, combining with its ultracold polar craters - that never see the sunlight - could also be acting as an "icemaking chemistry lab". In their new study, to be published in the journal Astrophysical Journal Letters on Monday, they modelled the complex conditions on Mercury, many of which are key to the ice making chemical process. "The process in our model would not be anywhere near as productive on the moon. For one, there's not enough heat to activate the chemistry," Jones said.
