|'One of the key aspects of finding life elsewhere is our ability to compare it to life as we know it, to compare it to the tree of life here on Earth and see whether that life represents a second origin of life in our solar system. Life on Earth is based on the same fundamental biochemistry, DNA, RNA, proteins. Whether you're a microbe at a hydrothermal vent, or a computer programmer at a software company, we all function on that same biochemistry.' So could life elsewhere function differently? 'I'm curious, is there another game in town? Is there another way to get the business of life done? To answer that question we need to go to places that could harbour life -- Europa, Enceladus -- these ocean worlds of the outer solar system where there is liquid water. These are the places that entice me the most.'|
