One set of scientists suggest this week that Rosetta's comet could have micro-organic life - another says no. Nearing the end of its ten-year journey to catch up with comet 67P/Churyumov–Gerasimenko, Rosetta's met with some controversy this week. Several astrophysicists from Cardiff and Buckingham Universities have spoken up at the National Astronomy Meeting in Llandudno, suggesting that 67P appears to have frozen lakes embedded within. This, they say, could mean that the comet could have organic debris on it. Not all scientists agree with this hypothesis.
