A 1990 experiment to test whether we could discern life on Earth remotely
I half expected this article to essentially say &quot;we wouldn&#x27;t know life if it hit us in the face&quot;, but happily the conclusion was that yes, we could see strong evidence for the presence of life on earth from Galileo.<p>Life in other places might be radically different from our own, and we might be looking for the wrong things - but it is good to know that our search is at least able to find what we are looking for.
