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.

Discover’s Best of Amateur Imagers

Wednesday, September 10th, 2014

Discover online has an article today about some of the best in amateur space imaging. Many of which have been featured here on Wanderingspace before like Gordan Ugarkovic, Emily Lakdawalla and Bjorn Jonsson to name a few. The last item from Bill Dunford of Riding With Robots is an image that he actually suggested NASA point their HiRise cameras at that location. He suspected they might find something interesting there and they did —flash water movement and evidence of avalanches.

In Saturn’s Rings Official Trailer

Tuesday, July 2nd, 2013


The long awaited official trailer for “In Saturn’s Rings” has been unleashed. Looking forward to this film for over three years now.

Mimas and Herschel

Thursday, June 6th, 2013

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.

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.

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 Death Star Moon in Great Detail

Thursday, May 20th, 2010

Commonly known by most as that “Death Star Moon” — Mimas, is seen here in the some of the finest detail ever (and seen here in sick detail). Flying to within 9,500 kilometers (5,900 miles) of the moon, Cassini captured the infamous Herschel Crater dead center in the still frame. Herschel, a feature which upon its originating impact, likely came close to shattering the tiny moon into another Saturnian ring.

The image itself is a mosaic of several high-resolution images carefully placed together to make a full disc image. The lower right hand corner segment is (sadly) in a much lower resolution than the rest, but I’ll bet you didn’t even notice until I pointed it out and ruined it for you.

Saturn Through the Eyes of Hubble

Friday, April 10th, 2009

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.

Gordan, King of Rock N Ice

Friday, January 30th, 2009

The King of Saturn imagery does it again. One of the key images that inspired me to even start this blog was the NASA officially produced image of Mimas against ring shadows. This one is pretty much just as stunning. Gordan has knocked out a few other Saturn images recently, all worth a look at his flickr stream.

Cassini Team Shows Some Color

Tuesday, October 16th, 2007

NASA released an unusually large amount of color images to the Cassini website recently. Most of what is shown here on this site are actually images put together by freelance imagers who access the raw files and do some stitching together of filtered images. Color images coming straight off the Cassini website are a rare event, so when about 8 appeared in the gallery a few days ago… it was an unexpected gift.

The Unlit Saturn
Saturn as seen from the unlit side of the rings.

The Saturn System
A family portrait of the Saturn System. Moons visible in this image (you need to click the preview) are Dione at far left, Enceladus near the left side ring edge, Mimas a speck on ring shadows on the western limb, Rhea against the northern hemisphere, Tethys near the right ring edge, and Titan near lower right.

Titan, Epimethius and the RIngs
Titan and a small moonlet named Epimetheus share the frame with Saturn’s rings.

Titan on the Edge
A rare color view of both Saturn and Titan in one frame. This is the only one of its kind thus far in the mission.

Rainbow in the Rings
A small rainbow appears as sunlight streams through Saturn’s rings.

Enceladus, Mimas Transit Saturn

Enceladus, Mimas Transit Saturn

Here is a recent set of raw Saturn images (red, green and blue filters) combined to create a near-true color shot. Moon motion in RGBOf course, the moons and Cassini were both moving and changing the perspective of the 3 bodies from one another from one filtered exposure to the next (the effects of which can be seen at left). So it was required that the 2 moons be “lifted” from the main image, properly registered for each individual moon and then merged back into the main composition. Once in place, a bit of Photoshop retouching was needed to erase the echoes in the 2 other channels where the moons were before registration was corrected.

The raw files archive on the Cassini site only reports which object was targeted, so it did not specify that the other moon is Mimas… but I cannot image what other globe that could possibly be seemingly inside Enceladus’s orbit.

Image Processors on Flickr: Gordan Ugarkovic

Friday, December 29th, 2006

Gordan Ugarkovic has a great collection of reworked Cassini images on Flickr. I contacted Gordan about showing some of his images here on wanderingspace and he was ever so gracious. As many people Gordan is “somewhat underwhelmed by the frequency the Cassini Imaging Team releases color composites”, so it is up to excellent freelancers like him to compile this information from the data files which are made public by NASA. Problem is that these images rarely make it to the mass media and we are stuck with the dozen or so color images the NASA imaging teams decide to produce in a year.

Wallpaper: Europa and the Eye of Jupiter

Wallpaper: Saturn’s Rings and Three Moons

WALLPAPER NOTE: The left 1/3 of the “Three Moons” image was extended in Photoshop using data at the edges of the original image which was cropped to a square format. This “fake” imagery was only applied to that area of the rings and the rest of the image including the moons is actual.

Here are some other images from Gordan which are some of my favorites, but don’t trust my editing… go to the gallery and have a look yourself. For the sake of posterity I have added a permanent link to his gallery on the right side of this blog where you may note that there are already a few others linked. There were two additional ones but the sites have been taken down since I linked to them?! Hopefully the three left will stick around for a while and I will in time add more to the collection.

Wallpaper: Saturn and Mimas
One of my favorite wallpaper images from the Cassini mission. This image almost looks like one of the fantastic Chesley Bonestell images from the 80’s only its not a painting. What you see are Saturn’s rings along the bottom and tiny Mimas floating across Saturnian cloudtops which are being shadowed by the rings. It is thought that these deep shadows, in addition to Saturn currently being in winter, somehow cause less clouds to form in Saturn’s northern hemisphere and create the blueish appearance seen here. When the Voyager’s passed by Saturn in the 80’s the entire globe appeared to be peach colored and lacked any of the blues you see today.

IMAGE NOTE: The left 1/5 of the image (the rings) is a digital extension of the image data found near the edge of the original image. This was done simply to fill out the proportion as the original was cropped to about 4/5 the the width.
