You need to upgrade your Flash Player The theme of this blog is not only and obviously space, but in particular “terrestrial worlds”, places that tend to have surfaces on which one could walk or at least attach oneself to. These places sometimes also have other earth-like familiar features such as atmospheres, weather, volcanos, geysers and perhaps, we are finding, even exotic oceans, rivers or lakes that are not necessarily made of familiar materials we are used to here at home. The second theme is imagery. Occasionally I do some retouching of images when needed if an image is incomplete or sometimes “dirty” or noisy. I will attempt to correct image shortcomings based upon other images or well-accepted presumed attributes. When this is done, notes will be offered as to what was added, why and sometimes how it was done. This way no one should ever wonder if something they are looking at is real or photoshop.

Life in the Hood: Titan

Once we leave the realm of Mars, Europa and Enceladus we have to entertain more fantastic possibilities for life elsewhere which are harder to imagine. Titan, it is assumed, would be far too cold all over (no warm spots here) for any form of life to ever take hold. However, this is assuming that all life-forms are carbon based and depend on water to survive.

On Titan we have what some call a much colder early Earth where methane plays the role that water does here on Earth. On Titan it rains methane and liquid methane collects on its surface to create rivers and even lakes. So what makes Titan an interesting subject in the conversation of where to look for life is only in that it seems so Earth-like. Compared to all the other bodies it is the only one that has almost everything Earth does – rivers, lakes, shores, volcanos, clouds, rain, lightning – an entire process that mimics the role water plays here on Earth only with methane instead, it even contains carbon compounds (the first essential to life). What if… in the remotest of possibilities… some form of life came to be here that instead thrives off of these elements? Perhaps all that life needs to thrive is a living planet which hosts materials that evaporate and make clouds which in turn rain those materials back down to the surface in liquid form to reshape and carve out the surface keeping it fresh. Who is to say that all life-forms in the universe need water and oxygen to exist? Why not sulfur? Why not Methane?

But life as we know it here at home is hardly likely on Titan. So far there is no evidence of water, temperatures or even oxygen to support a more earthly organism for even a scant of a second. Finding life in a place like Titan would be far more revolutionary than finding it on Mars, Europa or Enceladus because it would have to be so totally different from all living things that we have ever seen. It would change the very foundations of what we thought we knew about biology… Don’t get me wrong, life anywhere apart from Earth would be mind-blowing and the possibility of comparing a life-form which evolved wholly apart from all living things on Earth would be a staggeringly exciting concept to just about anybody. But discovering a life-form so totally independent from all the rules of Earth based biology would not only be fascinating, but it would also more or less verify that the universe is indeed lousy with all kinds of life-forms and would also many-fold increase the likelihood that somewhere out there are intelligent beings with which we may one day be able to communicate with. A situation that would suddenly turn science-fiction to fiction.
