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.
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.
Gordan of course.
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.
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.
More coming. Looks like a nice encounter.
Gordan U compiled this image of Enceladus lit both by Sun and Saturnshine. The side lit by reflected light from Saturn is in infrared and in the original appeared in a green hue. I took some liberties and imaged it as I would imagine it really would appear to the eye in Saturn’s more orange/yellow hues.
Worth noting tomorrow the images are due in from Cassini’s closest approach yet through its plumes. Hoping for some amazing material.
Seen in this image are Enceladian surface features and it’s geysers in action. This is normally not possible as the geysers are not normally visible unless they are back-lit… which they are in this image. The difference is that the surface details of Enceladus are being lit by an additional light source: Saturnshine. This makes for a fairly rare view where both details can be seen in one view.
Not to re-post old material, but our iPhone planetary skins were recently posted to fuelyourcreativity.com for free download. So I thought I would just remind everyone and maybe direct a little traffic love their way.
Some recent posts from Gordan Ugarkovic. The first is just gorgeous, the second featuring Prometheus and Pan in the gaps, the third is also just real pretty and the 4th is two sides of Enceladus. The 2nd and 4th of these images are false color which we publish less often, but these were just too nice to deny.
You may have seen this already, but we were keeping it on the side for a slow image week. What makes the photo more exciting than the hundreds of Cassini images coming back daily, is that you can see 4 of Saturn’s moons as well: Titan, Enceladus, Mimas and Dione.
It is true. You can become friends with all the best moons on Facebook these days. Who wouldn’t want to get closer to Io. Maybe get to know better Jupiter’s moon Europa. Maybe you live in the same Solar System as Enceladus?!
Sorry for the delay on this one… its remarkably similar to the last close approach images from August. This image, taken from 1,691 kilometers, also shows the areas surrounding the plume sources to be boulder strewn which suggests that occasionally some large sized chunks of internal Enceladus are ejected from within.
This approach and the previous only weeks ago are to be combined as a double research header. This encounter was largely for hi-res imaging while the previous was to “sniff” out the chemical composition of those plumes. The next close encounter (like this) for Enceladus will not be for another year, so lets hope these two encounters give us a clearer picture of what is actually happening inside this small wonder.
Check out this massive composite of the encounter released by JPL:
There was another up-close buzz over the plumes of Enceladus yesterday. Apparently the science team has been mum about the previous close shave a few weeks ago because they want to do a combined press release on both encounters.
The above image taken Oct 28, is a real nice warm up shot taken on its way to the encounter with Dione in the foreground.
Images should have been out by now, so far only a small hand-ful. As mentioned previously, this was not going to be a image rich encounter.
