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.
Having followed the activities of a small army of freelance space imagers that lurk in various places on the internet for about 10 years now — it is truly unusual for me to come across images that I know I have not seen before. Michael Benson’s exhibit titled, “Planetfall” at the American Association for the Advancement of Science offers offer fresh views from missions as old as Viking and as new as Cassini. What originally caught my attention was an image of an actively spewing Enceladus that is exposed in both Sun and Saturn shine — a view I have surely seen before, but never so detailed or dramatic. Even more surprising and rare is a new global composite view of Uranus with a complete and continuous ring taken by Voyager almost 30 years ago.
The show ends soon (June 28, 2013) and is located in Washington DC.
Herschel is a huge crater in the leading hemisphere of the Saturnian moon Mimas, on the equator. It is the one that makes Mimas look like The Death Star. This is the best image yet of this feature taken by the Cassini probe.
