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.

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.

Planetfall

Tuesday, June 18th, 2013

Having followed the activities of a small army of freelance space imagers that lurk in various places on the internet for about 10 years now — it is truly unusual for me to come across images that I know I have not seen before. Michael Benson’s exhibit titled, “Planetfall” at the American Association for the Advancement of Science offers offer fresh views from missions as old as Viking and as new as Cassini. What originally caught my attention was an image of an actively spewing Enceladus that is exposed in both Sun and Saturn shine — a view I have surely seen before, but never so detailed or dramatic. Even more surprising and rare is a new global composite view of Uranus with a complete and continuous ring taken by Voyager almost 30 years ago.

The show ends soon (June 28, 2013) and is located in Washington DC.

Titan Looking Very Earthlike

Wednesday, May 18th, 2011

It is false color, but seeing that really does remind one of Earth.

Dueling Enceladian Light Sources

Monday, November 2nd, 2009

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.

Mariner 10 Re-Imaging of Venus

Sunday, July 19th, 2009

Been meaning to catch up on a few odds and ends lying around. This image of Venus was re-worked from Mariner 10 images by Mattias Malmer somewhere around 2005. It is an attempt at showing Venus in natural light and is far better than the version previously used as our “portrait” image for Venus. The issue is that Mariner 10 images only allow one to do that by taking some liberties with UV data. According to Malmer, “I think that if I were to make an even blander version of the this image it would be close enough to reality”.

See the original 2005 post on unmannedspaceflight.com where you can get this image at 4000×4000 resolution. Time for a wallpaper update.

More Gordan U

Friday, May 8th, 2009

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.

Saturnati XX

Saturn in near infrared filter. Taken late March 2009.

MAD Infrared Jupiter Image

Saturday, October 4th, 2008

Jupiter in infrared light

“Jupiter in infrared light, taken on the night of 17 August 2008 with the Multi-Conjugate Adaptive Optics Demonstrator (MAD) prototype instrument mounted on ESO’s Very Large Telescope. This false colour photo is the combination of a series of images taken over a time span of about 20 minutes, through three different filters (2, 2.14, and 2.16 microns).”

See Centauri Dreams for more.

Express Way to Venus

One More Earthrise

Too few images come from the Venus Express mission. Probably has something to do with its featurelessness. The only way to see this level of detail in the Venusian clouds is by using alternative flase-color imaging. These frames were taken in ultraviolet light.

False Color From Phoenix

False Color From Phoenix

Until we locate some better “true color” images from Phoenix, this false will have to do.

Titan Descent in Stages

Titan Descent Images

Best compilation of Titan colorized descent images I have seen yet from NASA. I do suspect the actual color of Titan - on the ground - would look less metallic than these do. All the color seen here is based upon educated guesses and applied over the black and white images returned by Huygens. There were no real color images taken by Huygens during descent.

I plan to do a long post on some amazing renders made for an Italian magazine based upon actual imagery and data… but I am so busy these days. It will go up eventually.

Phobos as Seen by MRO

Wednesday, April 9th, 2008

Phobos from MRO

This is a semi-false color image as explained on NASA’s site, “The High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter took this image of the larger of Mars’ two moons, Phobos… on March 23, 2008. Taken from a distance of about 6,800 kilometers (about 4,200 miles). It is presented in color by combining data from the camera’s blue-green, red, and near-infrared channels”.

So there is some exaggeration of color here by including the infrared. I am guessing that is what is making the contrast between the reddish hues and those whitish marking at the edge of Stickney Crater. Click to see the hi-res… this may be the sharpest most detailed of Phobos I have seen yet.

Full Disk Rhea

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.

A Triple!

asteroid 2001SN263

Just in time for Valentine’s Day… a ménage à tous! Aricebo captured this radar image of asteroid 2001SN263 which turned out to be a triple asteroid. This is the first near-Earth object found to have more than one moonlet. Is it just me or does that main asteroid seem orb-like?
