"Astronomers have found three previously unknown moons in our solar system — two additional moons circling Neptune and one around Uranus."

AP reports: "The distant tiny moons were spotted using powerful land-based telescopes in Hawaii and Chile."

I still say #Pluto is a planet (it has several moons, thin atmosphere, semi-complex geology, & most importantly, human favor), but whatever.

That said, I wonder if the other planet is an ice giant like #Neptune & #Uranus or a super #Earth

2/2

To celebrate this Cloudy Ice Giant, I created a quick animation using the last three images of Uranus taken by ESA/NASA Space Telescope.

Full size images and more info here: https://flic.kr/s/aHBqjAgNJy

The images in the animation were taken during a period of 1 year:

  1. 2023/02/06 https://flic.kr/p/2oUiuJJ

This is very interesting... Our solar system's planet, #Neptune does not have the deep blue colour it is depicted with, as I can recall from seeing it in textbooks. It very much resembles #Uranus , in actuality. I guess the artificial colour enhancements helped to differentiate the two. And, you know, it's good that the true colour of Neptune is more like the shade of #PrinceNeptune 's first book, which is a pale teal. Seems much more fitting and appropriate, now.

Hold Onto Your Hats: Unveils Unprecedentedly Crisp View of And Its Rings
Uranus is an especially odd planet in our solar system because it rotates basically on its side at an angle of 98 degrees.
That gives it the most extreme seasons, a Uranian year lasts about 84 Earth years. Due to Uranus's wonky tilt, the sun only shines on one pole for a quarter of an entire Uranian year, leading to a very long winter that lasts 21 Earth years.

Don't look so blue, #Neptune: Now astronomers know this planet's true color : #NPR
Scientists have re-examined the filters used to make close-up photographs of the two planets and #Uranus isn’t the color you think it is. #astronomy

"For decades, images taken of Neptune have looked like the planet has a deep blue hue, while Uranus seemed more green. However, these two ice giants may actually look more similar to each other than astronomers previously believed."

Turns out, we may have been mistaken in how we’ve viewed Neptune this whole time. For decades, scientists have wondered why Neptune and Uranus, extremely similar in most ways, were such noticeably different colors. Now, however, scientists have reprocessed data and revealed that the two planets are actually very close in color.

Color processing in space imagery can be tricky. For example, the colours of Uranus and Neptune; You all know the famous Voyager 2 images of both and the stark contrast of shades of blue. Well, it turns out that they have the same shades of blue. As usual, it has sparked an amusing debate online.

I must admit, this news about and has me shook:

"A fresh analysis of Voyager 2's images show both ice giants are in fact a similar shade of greenish blue, which is the 'most accurate representation yet' of the planets' colors, the new study finds."

: What better way to finish out the week than with this new image of Uranus taken by the JWST? Taken with NIRCam (Near-Infrared Camera), the picture shows the planet and its rings in new clarity. The planet’s seasonal north polar cap gleams in a bright white, and Webb’s exquisite sensitivity resolves Uranus’ dim inner and outer rings, including the Zeta ring—the extremely faint and diffuse ring closest to the planet.

Tonight’s target on the dog walk. Uranus looks like a relatively easy target these days. Find the Pleiades, down and to the right, then follow an arc of bright(ish) stars to the last one, which will be the planet. Should be easy with binoculars. Less easy if my dog gets impatient 😄

NASA's Webb captures Uranus in unprecedented detail, unveiling 13 rings and nine moons, providing groundbreaking insights into the ice giant's dynamic atmosphere.

Okay y'all. Be honest. Who had the better picture of Uranus. Me or JWST? I know it's a close call...

Tonight in low-tech hunting: is there (center), and that's about all I can say about that

(bottom center) below the last night, a bit later, more exposure and more frames than the previous shot. Again somewhat fake: Composite of the same stack aligned separately on the moon and stars.
Also visible: , Callisto, Ganymede, maybe Europa if you squint at the glare around Jupiter, and (relatively bright blueish object almost directly above Jupiter)
