    Engineers explore ways to sample and identify living microbes in the outer solar system. Digital holographic microscopy, which uses lasers to record 3D images, may be our best bet for spotting extraterrestrial microbes. No probe since NASA’s Viking program in the late 1970s has explicitly searched for extraterrestrial life – that is, for actual living organisms. Rather, the focus has been on finding water. Enceladus has a lot of water – an ocean’s worth, hidden beneath an icy shell that coats the entire surface...

    A serendipitous detection of the organic molecule methanol around an intriguing moon of Saturn suggests that material spewed from Enceladus undertakes a complex chemical journey once vented into space. This is the first time that a molecule from Enceladus has been detected with a ground-based telescope. Dr Emily Drabek-Maunder, of Cardiff University, will present the results on Tuesday 4th July at the National Astronomy Meeting at the University of Hull.
