Results from a mass spectrometer on board the Philae lander revealed 16 organic molecules in the surface of the comet Churyumov-Gerasimenko, according to a report in Science. The article is part of a special issue on the comet. The spectrum was recorded about half an hour after the first touchdown and shows four compounds never observed before on comets. Most of the organic compounds contain nitrogen, but not sulphur. The observed molecules include acetone, propionaldehyde, acetamide, glycolaldehyde and etylene glycol. Science has collected other results in his Rosetta web page. Unfortunately these initial results might be also the last since Philae does not communicate since July 9.
