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.

Outer Space Art Film Uses Only Raw Images

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.

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.

Enceladus in Saturnshine

Wednesday, February 15th, 2012

Ian Regan’s composite of the recent Enceladus flyby. Best yet image I have seen of Enceladus lit both by sunshine and light reflected off Saturn (aka Saturnshine).

Also the Gordan Ugarkovic image. Note the spewing geysers on the lower left.

Best Color Image or Geysers on Enceladus

Geysers on Enceladus
Brought (as always) to us from Gordan Ugarkovic.

Saturn Cloudtops and The Fountains of Enceladus

Sunday, July 17th, 2011

Wow. That is quite a mutual event. Saturn crescent haze about as dramatic as it is ever seen by Cassini but with the addition of an active Enceladus hanging above at such a scale is quite unreal. Color by Gordan Ugarkovic.

Enceladus Sprays the Stars

Enceladus in Jan 2011

Taken in January of 2011 this raw image reveals Enceladus actively spraying the heavens from its southern geysers.

Mimas Wanders Into the Frame

Monday, December 27th, 2010

The Saturnian moon Mimas wanders into the frame of this shot which was primarily observing the active geysers on Enceladus.

The Plumes of Enceladus

Wednesday, October 20th, 2010

Back and front lit plumes

This is the best lit image taken of the plumes of Enceladus thus far by Cassini. The moon is lit from the front by Saturnshine and the plumes are being back-lit by the Sun directly behind. A perfect alignment for revealing active geysers on a small moon.

Sometimes Raw Images are Enough

Raw image of Enceladus

This image is taken directly from the Cassini raw images directory. Sometimes they are perfect with no need for adjustment or correction. The best detail is the subtle haze of the geysers spewing on the right edge. Taken April 26 from 987,839 kilometers away.

Okay, Set Scene: Rings, Titan, Geysers…

Thursday, June 24th, 2010

This composite has been kicked around a bunch on unmannedspaceflight.com. Contained within it are two separate images taken by the Cassini mission at nearly the same time but different exposures. Looking at this scene with human eyes, the big difference would likely be that the geysers would not be blown out and would look more like a multiple of gentle hazes spewing upward. The other big difference would be that you were somehow on a mission to Saturn and not browsing the web.

Above are the two original exposures. These were merely combined with a photo editing tool. The geyser haze was blurred in areas to clean out compression artifacts and the color was artistically added by Gordan Ugarkovic. While the color is artificially generated, it does accurately reflect the same overall appearance of most natural light images of Titan.

Through the Plumes!

Gordan of course.

The Fountains of Enceladus

Friday, November 27th, 2009

This has to be one of the greatest, most alien images ever taken from robotic spacecraft. It approaches how I might expect Enceladus to be depicted if it were in a Star Trek movie. As if the plumes at the edge of the disk back-lit by the Sun were not enough… the trail of smaller plumes breaking through the darkness is absolutely fantastic. The above is a real image but the color is an artistic interpretation by someone would know. Considering how little color is usually found at Enceladus, we can image this is really as good as if it were compiled from a full RGB set of filters. A larger monotone of the same image here.

This image was compiled by Astro0 on unmannedspaceflight.com. Also one of the best views staring down the length of one of Enceladus’ “tiger stripes”.

Ever so sharp look straight down on the South Pole of Enceladus from 1,855 km.

The Plumes of Enceladus in Color (kind of)

Friday, November 6th, 2009

Like the Saturnshine image posted earlier, this is only an estimation of a true color image. Five sources were used to compile this image; clear 1, clear 2, red, blue and another clear filtered image was used to replace the missing green to round it out (this work by S_Walker from unmannedspaceflight.com). We then additionally cleaned out artifacts from the original images and blurred the surrounding geyser haze largely to eliminate posterization noise.

This is the first time anyone has been able to attempt a true color view of the geysers with the availability of the red and blue images. Also a bonus is the considerable amount of Saturnshine seen on the dark side of the moon.

Enceladus at 9,988 km

More coming. Looks like a nice encounter.
