Titania is the largest of the Uranian moons. While Voyager couldn't fly close to it and still get to Neptune, it recorded more images of it than any other moon. The surface appears cratered with some clear tectonic features. The highest resolution images were at 4.5 km/pixel.

In addition to Miranda, Ariel, the next-innermost major moon of Uranus, received a decently close flyby from Voyager in 1986, revealing a complex, tectonically altered, and just-possibly active moon.

Flying by Miranda with Voyage 2 in 1986. Forty years ago, this moon, with its jumbled surface, awed the world.
From a day out, the fact that this isn't a cratered, dead world was becoming clear. The best color view, taken before closest approach. I am showing it here in black and white for consistency with the other images. The high resolution mosaic from closest approach. The best images are at about 250 meters/pixel. Just after closest approach, Miranda began to fade into the black of space.

Like I thought, my account on the old site is basically a zombie account with phantom followers now. Which means there's no reason to save it in case the site is sold.

Today in 1986, Voyager 2 made humanity's first and only encounter with Uranus, revealing its clouds, rings, and fascinating zoo of moons.
Uranus and its rings as Voyager approached it from the south Uranus, enhanced to make discrete clouds visible The rings of Uranus in a deep exposure. The spacecraft tracked rings, so the stars are smeared and appear as trails. The major moons of Uranus to scale.

From NASA:

Get my good side! In 2016, our Cassini spacecraft was still orbiting the ringed giant, Saturn. Here's one of our favorite posts from that year.
The planet Saturn, seen from nearly directly above, against the darkness of space. The planet is circled by bands of colorful, golden-toned clouds. It rings appear as hundreds of thin, concentric circles around the planet with several dark gaps in the pattern. Saturn casts a shadow over the rings on the left side of the frame. Near the center of Saturn's disc is cloud pattern in the shape of a hexagon. Image: NASA/JPL-Caltech/SSI

239 years ago, William Herschel discovered Oberon & Titania, the largest Uranian moons. All but a few of Uranus' moons are named after characters from Shakespearean plays. Oberon and Titania pay homage to the fairy king and queen in "A Midsummer Night's Dream"

This is much needed. The Hubble Space Telescope will turn 36 this year, and the James Webb Space Telescope does not see in the visible area of the spectrum except the very reddest part. There is no space telescope of this capability in the works from any agency in this time frame.

Ganymede, moon of Jupiter, on March 4, 1979, from Voyager 1. At the top are the component images used to to create the final image. They have been colored to indicate what filter was used for each image.
Ganymede from the approaching Voyager 1. This was produced using images taken through Voyager's Violet, Orange (it was red-blind), blue, and green filters.

I might be biased, but today the South Polar Cap of Mars looks a lot like Scotland to me 😂

View of the south polar cap on Mars. A large bright white ice-covered area sits at the center, with an uneven, jagged shape that the author says resembles Scotland. Dark, winding lines of exposed terrain cut through the ice. The surrounding surface is reddish-brown with smoother textures.

3/3 If you’ve been following my work this won’t come as a surprise. I’ve once again updated the family portrait of the Solar System’s giant planets captured in near infrared by JWST

Full size+info flic.kr/p/2oUkYSY 🧪🔭

I’ll keep updating it whenever an improved version of these giants is released🙂
The image is divided into four sections, each showing one of the gas giants against a black background. Top left: Jupiter. It appears as a large, round sphere with horizontal bands in shades of light brown, tan, and white. A bright white oval storm sits on the lower right side. A faint ring is visible alongside Europa, one of its satellites, which appears very bright with a star-shaped artifact. Top right: Saturn appears as a pale gold/brownish sphere with horizontal bands, encircled by a bright whitish, thin oval ring system. The atmosphere is showing off a few circle whitish storm-like features. Bottom left: Uranus. It appears as a smooth blue-green sphere with some whitish circular clouds around the pole that is facing the observer. Surrounding it is a bright circular ring system made up of thin white lines. The rings form a bright, symmetrical halo around the planet. Bottom right: Neptune. It is a blue sphere with slightly brighter and darker circular features on its atmosphere. It also has a thin ring system, dimmer and less defined than Uranus’s in this image, appearing as a faint double oval around the planet. Each planet has its name printed below it in white capital letters.

Today in 1989, the Space Shuttle Atlantis launched the Galileo spacecraft, the first orbiter and entry probe at a giant planet. When I watch it recede from the shuttle, I can't help but want to scream to open the antenna first (it never opened). They were still able to salvage an amazing mission.

In this view, Europa is eclipsed by the planet Jupiter, which is why it is so dim relative to the rings. Callisto, moon of Jupiter from the Galileo orbiter.

A high-resolution color image of Mars with the small, dark, potato shaped satellite Phobos, seen in sharp contrast as it passes over the massive volcano Olympus Mons. Phobos appears irregular and shadowed against the softly rust colored Martian surface. In the distance, two other volcanic features Ascraeus Mons (upper right) and the flatter Alba Mons (upper left) are visible. Wisps of light clouds and the blackness of space frame the planet’s curved horizon.

Jupiter is next on the list to be updated :)

A faint ring is visible alongside Europa, one of its satellites, which appears very bright with a star-shaped artifact. Top right: Saturn. It has a pale beige surface with soft horizontal shading. Surrounding it is a wide, bright ring system tilted diagonally. The rings look thin and sharply defined, with multiple subtle bands of light and dark. Bottom left: Uranus.

@spacemarschall.net if going with an image from that paper, I would suggest our “true” color reconstructions. Very approximate true color, SHARK-VIS in February didn’t have a proper blue filter but a general purpose “visible” filter. Hopefully to be remedied in time for the next Jupiter oppo
Two images of Io acquired by SHARK-VIS camera on the Large Binocular Telescope. Left image shows the trailing hemisphere, including the red ring around Pele. Several dark splotches visible from ash fall deposits from Pele and Babbar. The right image shows the anti-Jovian hemisphere with Prometheus in the middle.
