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.
