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.

When It’s a Jet, It’s a Jet All the Way

Comet Churyumov-Gerasimenko (aka CG-67P) is showing the early formation of it’s jets. Those jets are what cause the formation of the most distinguishing characteristic of any comet — it’s tail. The Rosetta spacecraft is currently in orbit about the comet and it is assumed that as the pair orbit closer to the sun, these jets will become much more active and should provide quite a show for us. The Rosetta team has also recently shared the potential landing sites for it’s Philae Lander in November shown here.
