I have just read What elements are a possible basis for life?and I find myself wondering whether instead of seeking advancedlife-forms at remote locales a La SETI, and perhaps fundamentallydifferently, we ought to be looking for similar microscopic lifeforms on comets that pass off-and-on.
Granted, a comet may be near absolute 0 for a lot of the time,but microscopic life-forms are known to be capable of survivinglean periods by using a cyst, for instance. As far as the rest isconcerned, comets probably contain some amount of ice, and hencewater, too. Similarly a comet's sprint around the sun could providesome limited amount of gravity/mass too.
So, should we be looking for life on comets?
