On August 2nd, 2007 Cassini executed an observation sequence with the cryptic ID given as ISS_048IA_MEETUSOON001_PRIME. A corresponding, more human-understandable sequence title was also given which is also the title of this image. It's clear this is one of those "Kodak moment" shots in anticipation of the Iapetus flyby roughly one month later. The wide-angle camera isn't able to close the 7.4 million kilometer distance to Iapetus from this vantage point (3.4 million km to Saturn) and the curious moon appears as just a small orb even to the 10x higher resolution narrow-angle camera (inset view). Other moons visible are Rhea at lower left and Tethys closer in to Saturn. Iapetus' brightness was increased for better visibility in both views compared to the rest of the scene. The image was taken half a Iapetan orbit before the only close flyby of this moon Cassini performed on September 10th. Approx. natural color RGB composite.

This is an approximate true color view of Saturn. Saturn's north polar hexagon stands out prominently while the planet casts a shadow upon its rings. This composite is made of images that were taken by Cassini's camera system, the Imaging Science Subsystem (ISS) on April 03, 2014 and received on Earth April 03, 2014. The camera was pointing toward SATURN at approximately 1,352,664 miles (2,176,902 kilometers) away, and the images were taken using the CB2, GRN, MT2, CL1 and CL2 filters.

NGC3269 is one of the most interesting galaxies in the Antlia Cluster. This appears to be an Sa spiral surrounded by several tidal loops and clumps. A particularly curious feature is a tiny 4 arcsecond wide brown dust cloud superimposed on the bright blue spiral arms. In the image above, on the left is a 2X enlarged crop of NGC3269. At the bottom right is a close-up taken with the 6.5m Magellan Telescope which shows the micro dust cloud in detail, including two additional very small patches each about 0.5 arcseconds wide. One of these is identifiable in my image, as can be seen in the 4X enlarged crop inserted at the top. These are suspected to be unique small foreground dust clouds of a previously unknown type. For more details on this peculiar feature see "A Tiny Galactic Dust Cloud Projected onto NGC 3269?", B. Dirsch et al. 2005 The Astronomical Journal 130 1141

Family portrait of our Earth-Moon system taken by the JANUS camera onboard ESA's JUICE spacecraft. This is approximately how it would appear to the human eye. I applied gamma correction to the image which is needed to correctly display a raw camera image on digital displays. This is also the reason why the original release looked so dark. I also rotated the image and upscaled it to 200% using spline36 resampling and applied a bit of sharpening. Since the Moon moved a tiny bit between the different filter acquisition I had to re-align the RGB channels for it. Thanks to ESA for providing a 16bit tiff of the image and making this processing possible. original: www.esa.int/ESA_Multimedia/Images/2024/09/Juice_snaps_an_...

JNCE_2023364_57C00022_V01 Capture time: 2023-12-30 08:37 UT Height above surface: 2839.6 km Jupiter's innermost moon Io as captured by the JunoCam instrument during Perijove 57. The image is processed in approximate true color as the human eye would see it. Using the spectral sensitivities of the RGB filters of the camera, the surface reflectance profile of Io (Karkoschka et. al 1995; Hapke et. al. 1989) and the CIE 1931 color matching functions, I computed a best effort color calibration matrix. A difficulty with JunoCam is that it's color filters/lenses have been altered from radiation, making the raw white-balance very inconsistent over time (bsky.app/profile/bjornjonsson.bsky.social/post/3lb4457uxm22t). I tried to account for this during processing, but the correction is only approximate. This image was processed from the raw framelets. They were calibrated with custom python script and assembled in PTGui.

NASA image acquired: March 29, 2011 This historic first orbital image of Mercury was acquired 37 years to the day after Mariner 10’s historic first flyby of the innermost planet. Labels have been added to indicate several craters that were named based on Mariner 10 images, as well as Debussy, Matabei, and Berkel, which were named based on MESSENGER flyby images. The surface contained in the white lines is terrain previously unseen by spacecraft, and the star indicates the location of the south pole. On March 17, 2011 (March 18, 2011, UTC), MESSENGER became the first spacecraft to orbit the planet Mercury. The mission is currently in its commissioning phase, during which spacecraft and instrument performance are verified through a series of specially designed checkout activities. In the course of the one-year primary mission, the spacecraft's seven scientific instruments and radio science investigation will unravel the history and evolution of the Solar System's innermost planet. Visit the Why Mercury? section of this website to learn more about the science questions that the MESSENGER mission has set out to answer.

An attempt to visualize what a green pea galaxy might look like if we could see one up close. Hubble recently took an observation of one, and it left me a tad dissatisfied. Did you know that there is no nearby example of a green pea galaxy, or anything even similar? Actually, these tiny smudges are considered nearby compared to, say, something twice as far away. What I mean is they are small enough and far enough away that we can't see any details. They are near enough to do spectroscopy though, which tells us a lot about them. I decided to illustrate how I thought it might look, but my first try needed some modification. After a brief Twitter exchange, Drs. Sangeeta Malhortra and William Keel set me in the right direction. Hate on Twitter all you want, but it's sometimes very useful! I used a combination of clone stamp painting for the star clusters and free airbrushing with my pen tablet for the green clouds/streamers. The base galaxy I modified was a real dwarf galaxy I processed a while back: flic.kr/p/XgFVxh There's a really great figure in this paper showing some pea galaxy details! They are still quite small and fuzzy, but some of the tendrils can be seen in some of them. Data from Gems of the Galaxy Zoos inspired this work. Specifically, observations jds42kcfq and jds42kceq. The original observed galaxy takes up about 21x31 pixels on the detector. If this was a real observation, it would probably use a combination of wideband near-infrared, visible green, and ...
