    New research has revealed that chemical reactions previously thought to be 'impossible' in space actually occur 'with vigour,' a discovery that could ultimately change our understanding of how alcohols are formed and destroyed in space - and which could also mean that places like Saturn's moon Titan, once considered too cold for life to form, may have a shortcut for biochemical reactions. A team at the University of Leeds, UK recreated the cold environment of space in the laboratory and observed a reaction of the alcohol methanol and an oxidising chemical called the 'hydroxyl radical' at minus 210 degrees Celsius....
