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.

Best of G. Ugarkovic (Last 8 Months)

Saturday, November 17th, 2012

If you follow this blog on any basis, you might be well aware that a good percentage of the imagery is provided by our good flickr friend Gordan Ugarkovic. Here is a bit of what we missed from him in the last 10 months we were locked out.

Titan at the edge of Saturn taken 2011-05-21. Looks unreal. Like Titan was dropped into the scene using Photoshop. A sin I would never commit. See the lesser “official” NASA version released a few months back here.

Keeping with the theme of moons transiting Saturn. Here is Rhea and tiny Epimetheus doing what they do. Taken in 2010-03-24.

Finally, just to change it up… two moons against Titan, another of Saturn’s moons. Pictured above the Titanian cloud-tops is Dione on the left and Rhea on the right.

Messenger, I Owe You Some Attention

Saturday, November 17th, 2012

To the casual observer Mercury is a body double of our own moon, but they are very different on the inside. In images, however, it offers very little that is unfamiliar from what we can see with our own eyes when we look up. Included in this post are 4 full color images of Mercury with the above being taken in February, 2012.

The above and image also from February, 2012.

Above image captured by Messenger in April, 2012.

Saturn’s Five

Wednesday, November 14th, 2012

Space enthusiasts seem to really like shots that have more than one body in the same frame. How about five… or six (if you count the rings of Saturn)? Starting left to right that is Janus, Pandora, Enceladus, Mimas and Rhea.

Thanks again to Gordan Ugarkovic.

Neptune Revisited

Monday, November 12th, 2012

Daniel Machácek does some modernizing of old Voyager 2 data at neptune. You can clearly see a shadow of one of Neptune’s moons at the top right edge and two others in the same area that are much less obvious. Interesting thing about data is that it is often better than the processing technology that happens to be available at the time the actual missions took place. Add to that the fact that there is a small army of talented freelance imagers like Daniel, the result is what feels like new images from old missions.

Titan’s Polar Vortex

Sunday, November 4th, 2012

Titan

Only a true lover of planetary exploration can get excited about an image like this. Titan is definitely one of the most exciting places in the solar system despite it’s almost total lack of discernible details either surface or in cloud structure. So like Uranus and Venus most images of these locales look something like smooth monochromatic tennis balls without the white lines.

Titan’s polar vortex in color

Above is a color image of the vortex in more detail. Scientists are still unsure of the process that causes this to occur. However, similar phenomenon have been seen before — most notably on Titan’s parent planet, Saturn.
