Glaciers made of acetylene ? on Earth, a gas used in welder's torches ? may tower over the polar regions of Saturn's moon, Titan, according to a new analysis. The region near Titan's north pole also appears to harbour huge hydrocarbon seas, new radar observations reveal. Jeffrey Kargel of the University of Arizona in Tucson, US, led a team that surveyed the zoo of organic chemicals known or suspected of being present on Titan. Then, the team analysed what form they might take in the ultra-cold, hydrocarbon-rich environment of the enigmatic moon. At the -180? Celsius temperatures on Titan, it is cold enough for acetylene, which is a gas on Earth, to freeze solid, the researchers say. For the full article Click Here .
