Analysis of rocks in the Outer Hebrides has provided a tantalising clue that Mars may contain habitats which can potentially support life.
Researchers studying rocks on Barra and the Uists have demonstrated that hydrogen – which is essential for life – is formed by earthquakes. On Mars there are ‘Marsquakes’ which may produce hydrogen in the same way.
The study, which has been published in the journal Astrobiology, was carried out by scientists from the University of Aberdeen, working alongside colleagues from Yale University and Brock University. Their research was supported by the Science and Technology Facilities Council.
