Saturn’s moon Titan just keeps getting weirder – and more tantalising when it comes to scientists’ hopes for life beyond Earth. Titan is perhaps the most Earth-like place in our Solar System, except the ingredients are jumbled up: ocean below ground, landforms of water ice instead of rock, rains of organic compounds and an atmosphere denser than our own. Now, two new research findings add still more intrigue to the strange moon, identifying an unexpected chemical in Titan’s atmosphere and evidence of more complicated surface phenomena than scientists had previously realised.
