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.
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.
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.
“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).”

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.
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.
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.
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?
The New Horizons team has made all the MVIC (Multispectral Visible Imaging Camera) images as well as the LORRI (Long Range Reconnaissance Imager) images from the Jupiter encounter available for imagers to kick around. The above image is by Gordan Ugarkovic and is apparently a “colorized” version of a monochrome he created using earth based observations of the planet from around the same time. In addition to the two moons (and a shadow), also visible are both the Great Red Spot as well as the “Red Junior” spot which has in recent months has become a new notable feature of Jupiter.
