Titan and Europa make wondrous targets in the search for alien life

its is a very good article about the Titan and Europa...

i accept that these bodies exibit a lot of geological activities(like rain, wind...)

but i dont see any possibility of biological activity because of these geological activities....

does anyone agree with me?

I don't agree with you. :-P Life can exist just about anywhere there is liquid water. If there's an ocean under the ice of Europa, then it'd be foolish to think it's lifeless.

You will be assimilated...bunghole!

Both are, after Mars, the best places in the solar system to look for life (past or even present).

Europa, with its buried oceans, may support multi-cellular life. There seems to be liquid water down there. I guess it is the tidal forces from Jupiter that is helping to heat Europa internally enough to support liquid water. Tidal forces weren't thought to generate so much heat until the surprising discovery of geysers on Enceladus was made.

Titan is interesting because it is so similar to early Earth. Its, somewhat, following the same evolution of early Earth, but in s-l-o-w motion because it is so cold there. It rains methane and amino acids on Titan. That, alone, is pretty cool. Titan was Sagan's baby. Sagan theorized that ammonia may have raised the freezing point of water in localized areas on Titan, so that there may be "puddles" of water, mixed with methane and amino acids. Another theory of his was that comet impacts may have generate enough heat to create localized "puddles" of water, methane, and amino acids also.

If vaporous geysers erupting 290 KM above the surface heat of some source other than the sun is creating pressure of enormas pressures to eject this material so far from the source. It also produces the faint e-ring of saturn. Enceledeus has these beautiful plumes. I would think in water life could be possible at a microbial level like on earth as long as it isnt too cold. The surface of the moons are below -300 degrees below zero at the surface. The eruptions of water vapor the water below the insulating ice surface has to be a liquid form. To maintain that for so long to form a ring that covers tens of thousands of miles I think I rmeber {145000} miles to form the E-ring of saturn the water would be not only warm but relativly hot to warm and maybe the resulting temperature differences react explosivily like throwing dry ice in water.
