Comets could be cosmic laboratories
Scientists say the Philae space probe has gathered data supporting the theory that comets can serve as cosmic laboratories in which some of the essential elements for life are assembled. Philae, which is part of the European Space Agency’s Rosetta mission, used two separate instruments to “sniff ” for molecules during its bumpy landing on comet 67P/Churyumov-Gerasimenko last November.
