Organic molecules detected by Philae

The Philae lander has detected organic molecules on the surface of its comet, scientists have confirmed.

Carbon-containing "organics" are the basis of life on Earth and may give clues to chemical ingredients delivered to our planet early in its history. The compounds were picked up by a German-built instrument designed to "sniff" the comet's thin atmosphere. Other analyses suggest the comet's surface is largely water-ice covered with a thin dust layer.

The European Space Agency (Esa) craft touched down on the Comet 67P on 12 November after a 10-year journey.
