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.

Titan and Rhea Together Again

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.

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.

50 Years of Space Exploration Map

Tuesday, October 13th, 2009

This is so nice, but I am furious that I didn’t get to design this. This is Information design at it’s best naturally by National Geographic. You can see 50 years of robotic planetary exploration at a glance. It even includes failed missions represented by darker desaturated lines. As far as I can tell the cream colored lines are US and the red ones are Soviet. Interesting to see how many of those lines go dark around Mars.

Now where does one purchase such a thing? Perhaps this month’s issue of NG? Here is the link to it on their site complete with zoom viewer and them some kind samaritan posted a hires version to flickr.

Partial Eclipse of Titan

Wednesday, September 23rd, 2009

A nice back-logged image I never posted. Rhea passes in front of Saturn’s larger, hazy moon Titan (which is lit from behind by the sun). Taken June of 2006.

Another Gordan Ugarkovic. It never ends!

Rhea in Great Detail

Rings at Rhea?

Saturday, March 8th, 2008

Some scientists believe that they have stumbled upon the first ever detected rings around a moon. As if that were not interesting enough — these theoretical rings would also be the only rings ever found around a body that is not a gas giant such as Saturn, Jupiter, Uranus or Neptune. As a matter of fact, Rhea isn’t even one of the larger moons of the Solar System. If these rings exist they are sparse and made of small particles, so Cassini is unlikely to ever detect these particles with the cameras its is equipped with. Therefore, there are no actual images to support this theory… but it is interesting enough that I feel compelled to at least point interested space fans to a great article explaining the theory on the Planetary Society’s blog.

Rhea composite from infrared, ultraviolet and green filters

Rhea composite from infrared, ultraviolet and green filters. So it’s not technically true color… but I adjusted it a touch to make it more natural. However, I must admit that having never actually been to Rhea myself… it’s an educated guess. Seems a bit blue.

Rhea and Dione, So Happy Together

Rhea and Dione, So Happy Together

Just been going through older files lying around that were never uploaded. This is a visible light composite that wanderingspace put together of Rhea and Dione a few months back.

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.

Rhea Transits Saturn

Sunday, October 7th, 2007

These images were taken of Rhea as it (and Cassini) sped across Saturn’s globe on August 30, 2007. The near-natural color images were composed from raw near-infrared, green and ultraviolet filtered files made available on the NASA-Cassini website. Some of the details may have been enhanced through the use of infrared and ultraviolet in place of red and blue… but they have been adjusted to reflect what we assume is closer to actual natural color.

Rhea in Transit 01From approximately 93,823 km.

Rhea in Transit 02From approximately 78,967 km.

Rhea in Transit 03From approximately 53,788 km.
