Wow..Been a while since I've surfed the Blue Oval Lounge. Jut my kind of debate, having a strong science back ground, and just as strong on intrest in astronomy I feel I must chime in.

Mr 5.0 made the comment about Life and its proxomity to us (earth). The Hubble Telescope was not designed for searching for extra terrestrial life (Single Cell, civilazations, what ever).

There are several places in our solar sytem alone that could possibly have life on them. One is Europa, an icy moon of Jupiter. Below its surface ice lays Briny oceans and slush. Europa has constant tidal forces stretching it. The jupiter and the sun constantly causing a tug of war which creates heat (Jupiters moon IO is very strong visual evidence of that process). They believe Europa has volcanic vents deep in its oceans that may spawn, and feed life such as our own oceans have and do. Some beleive, though fancifull thinking in my book, that it may be beyond simple celled organsims and have progressed to aquatic life similar to that that is in our seas.

Titan, a moon of Saturn is the only moon in our system to have an atmoshpere (Mostly methane..dont light a match =) )..and its in between the pressure of earths and venus (Quite a range there). It has mysetrious reflective spots on its surface that can be attributed to lakes of natural gas. The gasses, and presence of storms also lead to the possibility of life..simple life. There are missions on the slate to go to titan..infact one is on its way there now.

I am personally excited by such things.

As for the hubble being used to detect life as mentioned earlier...has anyone here seen a picture of Pluto taken by the Hubble??? You'd be surprised. No details are resolved, for the Hubble does not have the optic ability to resolve details of such a small object at such a distance. It is not going to see a planet directly thats around another star..no matter how close it is. It can detect the tug that a planet does on the star, because the star will woble, it can also detect when a planet gets between the star, and us by a change in light emitions, and spectroscope readings (Thats how they can get an idea of what the planets atmosphere is)...other than that..thats it.

I believe that there is life out there..and intelligent life at that. I am willing to bet money on it...now if we ever contact it in my life time..thats another thing.

We dont know as much as we could, or as much as most people think. We can blame funding and budgeting for that.

Well, I would love to type more, but I have to get back to work now.
