What a strange apparition from the Webb Telescope via Astronomy Picture of the Day for 13/10/22.
The apparent rings are thought to be dust shells but their formation process is unknown.

An amazing picture (via Astronomy Picture of the Day for 30/8/22) from the James Webb Telescope.
It is an unusual image of the Solar System’s largest planet but is unmistakable due to the large swirling storm at the bottom right (which in visible light is known as the Great Red Spot.)
Also notable are Jupiter’s rings, not normally easily discernible, and its southern and northern aurorae – not to mention two of its smaller satellites.

It’s not often you see an image of Jupiter’s ring.
This picture (from Astronomy Picture of the Day for 20/7/22) though shows both planet and ring in infra-red light as captured by the James Webb Telescope.
Also prominent is the Great Red Spot as a bright white feature in infra-red and the moon Europa at the centre of a large diffraction spike.
