Space chemistry could be cooking up icy building blocks of life, study says

Where did the ingredients for life on Earth come from? Many scientists think the basic chemical building blocks for biology were delivered via comet, but the building blocks -- and the building process -- remain a mystery. Now, a team led by French researchers thinks they may have found lab-based evidence that a class of complex organic molecules could have evolved in the ice of star-forming clouds -- and could be a potential source for the organic matter that allowed life on Earth to emerge. The findings, published in in Proceedings of the National Academy of Sciences, could also offer a chemical tip sheet for the European Space Agency’s comet-chasing Rosetta mission, giving it...
