Thanks a lot for the explanations !
The caption didn’t mention the moons and from the doublets or triplets on the picture I had the impression of seing 6 to 8 different and was wondering which one they are so close to the rings. Pictures are Beautiful !

Last night, the JWST observed Uranus for calibration. Even like that the result is awesome, so here you go with my processed image of that observation! 🔭

HD: flic.kr/p/2ry78y3

Observation of Uranus by the JWST. The planet itself appears mostly blue, but the pole, a big patch, is white. Some storms can also be spotted near the pole. The rings of the planet can be spotted in infrared light, so they appear in that image (in orange color).

Is there a way to know which moins were imaged ? Really Impressive pictures ! Congrats !

I also made an animation of the rotation of the planet. This also uses the F162M filter.

Merci pour les explications, c'est toujours passionnant. Mais finalement, pourquoi est-il parti à Yale ? Que pouvait-il faire la bas qu'il ne puisse faire au CEA ?

La Terre fait un tour sur elle-même en 23h 56mn 4sec. C'est ce que l'on appelle le jour sidéral. Comme elle tourne aussi autour du soleil, il faut 24h pour revoir le soleil dans la même direction!

A few hours ago, Comet 3I/ATLAS passed about 28 million km from Mars.

This was the best opportunity we'll have to image the interstellar visitor from spacecraft.

When those data are available, I'll share them!

Magnifique image de la petite lune Déimos avant l'aube martienne, capturée par le rover Perseverance.
Le soleil était 13° sous l'horizon et nous aurions vu un paysage très sombre faiblement éclairé par Déimos.
Un superbe travail de traitement d'images par Simeon Schmauß.

This photo from the Perseverance rover captured in early March, may be my favorite Mars image from this year.

It shows Mars' smaller moon Deimos over the hills of the Nili Planum region in the dark skies before dawn. 🔭

A picture of Mars taken during astronomical twilight (the sun was 13° below the horizon). It shows a dimly lit reddish landscape with some hills at the horizon. Deimos, Mars' smaller moon shines with a small halo in the pale sky above.

It looks like there are four planet like spots in the inner space. But they are not adressed in the caption. Are those planets also ?

Saturn, rings, and moons on August 30-31, 1979, from Pioneer 11 as it approached the planet. This was produced using images over a two and half hour period that spanned from just about midnight on August 30th into the wee hours of August 31.

Saturn from the approaching Pioneer 11. During this approach humanity saw the night side of the rings at an angle unachievable from earth (although the night side can be seen at times near a ring plane crossing, but the rings are much closer to edge on). Titan can be seen to the upper left, and a smattering of other moons made cameos.
