MICROSCOPES revolutionised the study of life on Earth. Now a rugged, easy-to-use instrument is aiming to be equally influential in the search for alien life in locations such as the oceans beneath the icy surface of Jupiter’s moon Europa.
The hunt for signs of extraterrestrial life usually focuses on detecting molecules associated with living organisms. Direct observation through optical imaging would be more conclusive, so Hans Kreuzer and Manfred Jericho at Dalhousie University in Halifax, Nova Scotia, Canada, and their colleagues have taken a different approach. They have built a robust…
