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.

Wallpaper: Triton Cryo-Volcanos
As of this time, Triton (a moon of Neptune) has the coldest temperature ever recorded in human history on any terrestrial surface… -235 C, -391 F. At these temperatures, nobody would have expected anything other than a huge frozen solid ice ball. Instead, Triton is littered with what we now call cryo-volcanos… or cold volcanos. They erupt or eject materials other than molten rock, such as water, ammonia or methane. As we are seeing in places like Titan (who is also suspected of having cryo-volcanos) many characteristics of Earth geology and weather are simulated elsewhere in the Solar System with different materials. On Earth it rains water, but on Titan it rains methane, and likewise on Triton it erupts probably liquid nitrogen instead of magma as it does here on Earth.

Only two active cryo-volcanos have been confirmed on Triton, but it is generally assumed that each one of those black smudges visible in this image are the remnants of recently active cryo-volcanos. There are quite a few…
