Pour le réveillon de ce soir il y aura une petite #conjonction entre la #Lune et les #Pléiades qui est un amas d'étoiles. Normalement visible sans instrument l'usage de jumelles sera recommandé. Pour la France métropolitaine il faudra observer des que le ciel sera sombre. Les Pléiades seront à droite et un peu en haut de la Lune. Pas loin se trouve aussi la planète #Uranus visible au télescope ou en photo longue pose.

Simulation Stellarium du phénomène représentant ce qu'il est possible de voir aux jumelles. La Lune gibbeuse (la phase entre le quartier et la pleine Lune) apparaît vers la gauche. À sa droite et un peu en haut quelques étoiles peu visibles, ce sont les Pléiades. Simulation pour 18h30 heure française.

Simulation similaire à la précédente mais ne prenant pas en compte l’éblouissement dû à la Lune. Les Pléiades apparaissent donc bien plus visibles. Le fond est rempli d'étoiles. Uranus est aussi visible comme l'une de ces étoiles à la droite de l'image assez loin des Pléiades et encore plus de la Lune. Elle reste toutefois dans la même partie du ciel.

Et voici (enfin) une photo du phénomène.

Canon EOS 700D, zoom 18-135mm à 113mm, 1s, f/5.6, ISO 800. Traitement Darktable. Appareil posé sur le rebord de fenêtre donc sans suivi (monture pas disponible).

Photo de la conjonction. A gauche de l'image la Lune apparaît éblouissante. Au centre un peu en haut l'amas d'étoiles des Pléiades apparaît. Elle est composée d'une douzaine d'étoiles sur la photo (en vrai il y en a une centaine mais la plupart sont trop faibles pour être sur la photo). D'autres étoiles sont éparpillées sur l'image. À droite et un peu en bas l'une d'elle, assez faible, est en fait la planète Uranus.

The image is divided into four sections, each showing one of the gas giants against a black background as seen by JWST. Filters are near infrared and have been colorised.

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. 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. 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. — The image is divided into four sections, each showing one of the gas giants against a black background as seen by JWST.

Image of Uranus taken by the James Webb Space Telescope, showing a whitish north polar region, vivid blue-greenish atmosphere and a few whitish elongated storms visible around the pole. The planet is surrounded by clearly defined ring system set against the black background of space.

Anton Petrov: New Moon Found Around Uranus

Although this very small moon is now officially called S/2025 U1, there are hopeful signs that it will be renamed to 'Trump's penis'. /j

From Voyager 2’s smooth blue-green view in 1986 to Webb’s breathtaking 2023 image, our vision of Uranus has transformed. Keck (2002) revealed faint rings, Hubble (2022) showed brighter tones and weather patterns, and Webb unveiled glowing rings and a luminous atmosphere.

Let's get this over with: Astronomers just found a new moon around Uranus.

It's part of an unusual group of 14 mini satellites orbiting close to the planet, within the orbit of its 1st major moon, Miranda. They may relate to the planet's rings & odd, sideways tilt.

Astronomers using NASA’s James Webb Space Telescope discovered a new moon orbiting Uranus in images taken by Webb’s NIRCam (Near-Infrared Camera). This image shows the moon, designated S/2025 U1, as well as 13 of the 28 other known moons orbiting the planet. (The small moon Cordelia orbits just inside the outermost ring, but is not visible in these views due to glare from the rings.) Due to the drastic differences in brightness levels, the image is a composite of three different treatments of the data, allowing the viewer to see details in the planetary atmosphere, the surrounding rings, and the orbiting moons. The data was taken with NIRCam’s wide band F150W2 filter that transmits infrared wavelengths from about 1.0 to 2.4 microns.

🪨 Scientists Say That Uranus Appears to Have a Girlfriend • Futurism

｢ In a new, yet-to-be-peer-reviewed paper flagged by Universe Today, an international group of researchers detailed finding a so-called "Centaur" — a small, icy and rocky body that sits between Uranus and Neptune and is designated as a minor planet — that appears to have been keeping up with Uranus in a delicate cosmic dance for thousands or even millions of years ｣
