Light + Electrons Busts Water To Bits At Rosetta’s Comet

An obscure but fascinating discovery was announced this week regarding Comet 67P/C-G, the 2.5 mile wide (4 km) island of dusty ice orbiting the Sun under the gaze of the Rosetta spacecraft. Water ice and carbon dioxide or “dry ice” make up a good part of many comets, including 67P. When those ices vaporize in the heat…
