Let's talk about alien life being found on Titan

[Hawaiian Punch]

Let's be clear Coli, it is happening, it will be found and it will change the world as we know it.

For the uninformed about Titan a few wiki factiods.

1-Titan (A Saturn moon) is the only known natural satellite (moon) in the Solar System that is known to have a fully developed atmosphere that consists of more than trace gases. Titan's atmosphere is thick, chemically active, and is known to be rich in organic compounds.

2- It has lakes, rivers, streams, clouds and rain. Difference from earth is that instead of water it's methane. Titan is a lot colder as well. Temps get as low as -212 F.

3- Organisms exist on earth called methanogens that eat hydrogen and produce waste methane.

Before any probe went to Titan scientists predicted that we could show life existed on it by measuring lower concentrations of hydrogen at the surface. Instead of breathing oxygen, organisms would breathe hydrogen. This was detected.

The reason why all this is important is Titan is completely alien to anything that exists on earth. Finding life here shows that life more than likely exists everywhere in the universe. That life conforms itself to the conditions of a world and water is not necessary. There's a reason they are all excited by this. There's a reason the ENTIRE scope of the Cassini mission changed.

Sounds good

 

[tmonster]

at some point nascence will become accepted as the statistical outcome of enough collisions between organic compounds
the next realization will then be just how big space really is

Have we discovered evidence for life on Titan?


by Chris McKay, NASA Ames Research Center, Moffett Field CA. (chris.mckay@nasa.gov)

Recent results from the Cassini mission suggest that hydrogen and acetylene are depleted at the surface of Titan. Both results are still preliminary and the hydrogen loss in particular is the result of a computer calculation, and not a direct measurement. However the findings are interesting for astrobiology. Heather Smith and I, in a paper published 5 years ago (McKay and Smith, 2005) suggested that methane-based (rather than water-based) life -- ie, organisms called methanogens -- on Titan could consume hydrogen, acetylene, and ethane. The key conclusion of that paper (last line of the abstract) was "The results of the recent Huygens probe could indicate the presence of such life by anomalous depletions of acetylene and ethane as well as hydrogen at the surface."

Now there seems to be evidence for all three of these on Titan. Clark et al. (2010, in press in JGR) are reporting depletions of acetylene at the surface. And it has been long appreciated that there is not as much ethane as expected on the surface of Titan. And now Strobel (2010, in press in Icarus) predicts a strong flux of hydrogen into the surface.

This is a still a long way from "evidence of life". However, it is extremely interesting.

Benner et al. (2004) first suggested that the liquid hydrocarbons on Titan could be the basis for life, playing the role that water does for life on Earth. Those researchers pointed out that "... in many senses, hydrocarbon solvents are better than water for managing complex organic chemical reactivity. Two papers in 2005 followed up on this logic by computing the energy available for methanogenic life based on the consumption of both the organics in Titan's atmosphere along with the hydrogen in the atmosphere (McKay and Smith, 2005; Schulze-Makuch and Grinspoon, 2005). Both papers made the case that H2 on Titan would play the role that O2 plays on Earth. On Earth organisms (like humans) can react O2 with organic material to derive energy for life's functions. On Titan organisms could react H2 with organic material to derive energy. The waste product of O2 metabolism on Earth is CO2 and H2O; on Titan the waste product of H2 metabolism would be CH4. As a result of the Cassini mission, there is now abundant evidence for CH4, even in liquid form, on Titan.

Organic molecules on the surface of Titan (such as acetylene, ethane, and solid organics) would release energy if they reacted with hydrogen to form methane. Acetylene gives the most energy. However this reaction will not proceed under ordinary conditions.

This is similar to our experience on Earth. Consider a chocolate bar in a jar full of air. The organics in the chocolate would release energy if they reacted with the oxygen in the air but the reaction does not proceed under normal conditions. There are three ways to make it proceed: heat it to high temperatures (fire), expose it to a suitable metal catalyst that promotes the reaction, or eat it and use biological catalysts to cause the reaction. Biology can thrive in an environment that is rich in chemical energy but requires a catalyst for the chemical energy to be released. Such is the case on Titan.

McKay and Smith (2005) predicted that if there were life on Titan living in liquid methane then that life should be widespread on the surface because liquid methane is widespread on the surface. We have direct evidence that the surface of Titan at the landing site of the Huygens Probe near the equator was moist with methane, and radar and near-infrared imagery from Cassini have revealed extensive polar lakes on Titan, both north and south. Methane-based life would have a lot of environments in which to live.

Nothing more than matter and energy developing a symbiotic relationship. It eventually molds and evolves itself to the environment that surrounds it. With enough energy the matter eventually becomes aware of itself. Some simple, so elegant, so infinite.

You watched that episode of How The Universe Works on Saturn and it's moons, didn't you?

Of course I did. I also follow the Cassini mission and damn near every craft in space. It bothers me that more people don't. Incredible times we are witnessing.

really? theres billions of planets out there, of course life will exist in one form or another

 

[JOHN.KOOL]

There is no life there. There is no life anywhere but earth

 

[observe]

What about the transit tubes and trees and face they found on mars

Really? Neg me?

In the time it took you to do that 3 other people gave me rep. And the earth ain't 5000 years old either. :stepehenausure:

Well there goes half of the worlds religions

God playin Sims out here

there has to be some reason for why they impose saturn worship on the people
