is space ice made of water?
« on: 07/04/2009 15:26:21 »




We always get worked up when we hear there might be water (liquid or ice) in other moons or planets, because the possibilities of the existence of life increase dramatically.
So, if there might be life in outer space where there is water, why donít we get all enthusiastic when we know that comets are made of ice, and that there is a lot of ice in space?   ???

It is liquid water that is a requirement for life (at least, life as we know it, Jim - sorry - another Star Trek reference). It is quite likely that there are loads of planets with liquid water but it is mainly the ones we can see close by (i.e. Mars/Venus) that are of interest. Venus is too hot and Mars is too cold but maybe beneath the surface there could be suitable conditions. There seems some evidence that Mars once had liquid water, which is interesting.

There is liquid water under the surface of Saturn's moon Enceladus ... http://science.nasa.gov/headlines/y2006/09mar_enceladus.htm

So theoretically chemosynthetic (rather than photosynthetic) life could exist there.
