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.

Europa

Europa has become a focal point of interest in our solar system. Subject to the same tidal forces that tear Io apart, Europa is less severely effected by this and here the stress takes the form of internal heating which keeps the moon from being frozen throughout. It has more-or-less been confirmed that below its icy crust lies an almost global ocean of 100% water. Considering that the center of the moon is quite warm and the icy shell is of course frozen rock-solid, somewhere in between must lie a zone with temperatures similar to that of earth deep within this watery underground ocean. As any marine biologist will tell you, the Earth’s oceans are riddled with life. Even in places of extreme heat and cold, life still somehow has survived the ages and has adapted to such extreme environments. Leading to conjecture that no-matter the obstacles to life ever developing on the surface of such a place… the mere presence of earth-like conditions deep within Europa’s dark underground water ocean may have been just enough for some if not many forms of life to evolve and survive to this day. There are many missions on the drawing board right now to find out more answers including a Europa orbiter, various landers and one truly aggressive mission that would involve melting through the crust and “injecting” a submersible probe into the watery core. For a new and improved portrait image of Europa see here.

    [...] The previous Europa portrait posted here, is the most commonly seen image of the full globe of Europa. Even though there have been multiple missions to Jupiter and its system of moons (including an orbiter which stuck around for quite a while)… there are surprisingly few full globe images of Europa. The one used in the previous post mentioned was compiled through several filters but due to some incomplete data, an artificial green haze appears at the right edge of the disc. Considering the scientific importance of Europa and its unique appearance makes a full globe view of this world highly desirable in my mind. [...]
