Panspermia advocates might derive some encouragement from the Rosetta findings from 67P/Churyumov-Gerasimenko about glycine (and some precursors) and phosphorous being identified in the comet's surrounds. But before opening the champers, it's worth remembering that earlier findings reported that the heavy water ratios on this comet were way out of whack with earth's - three times heavier I think) somewhat dampening the ardor of those who were suggesting that such comets delivered our water and other life ingredients to us.
Still, the latest findings do seem to point generally towards life chemistry as being possible out there. Add a little heat or other form of energy and "hey presto ".
