APOD: The Colors of Saturn from Cassini (2020 Mar 30)

Image The Colors of Saturn from Cassini

Explanation: What creates Saturn's colors? The featured picture of Saturn only slightly exaggerates what a human would see if hovering close to the giant ringed world. The image was taken in 2005 by the robot Cassini spacecraft that orbited Saturn from 2004 to 2017. Here Saturn's majestic rings appear directly only as a curved line, appearing brown, in part, from its infrared glow. The rings best show their complex structure in the dark shadows they create across the upper part of the planet. The northern hemisphere of Saturn can appear partly blue for the same reason that Earth's skies can appear blue -- molecules in the cloudless portions of both planet's atmospheres are better at scattering blue light than red. When looking deep into Saturn's clouds, however, the natural gold hue of Saturn's clouds becomes dominant. It is not known why southern Saturn does not show the same blue hue -- one hypothesis holds that clouds are higher there. It is also not known why some of Saturn's clouds are colored gold.

Jovians look down on Saturnians as pallid.

I really love photos of Saturn (doesn't everyone?)
This one is a beauty. No earth-bound telescope could ever get this shot.

https://en.wikipedia.org/wiki/Asmodeus wrote: <<Asmodeus (Ancient Greek: Ἀσμοδαῖος, Asmodaios) is a prince of demons, or in Judeo-Islamic lore the king of the earthly spirits mostly known from the deuterocanonical Book of Tobit, in which he is the primary antagonist. In the Binsfeld's classification of demons, Asmodeus represents lust. The demon is also mentioned in some Talmudic legends; for instance, in the story of the construction of the Temple of Solomon.

The Asmodeus of the Book of Tobit is hostile to Sarah, Raguel's daughter, (Tobit 6:13); and slays seven successive husbands on their wedding nights, impeding the sexual consummation of the marriages. He is described as 'the worst of demons'. When the young Tobias is about to marry her, Asmodeus proposes the same fate for him, but Tobias is enabled, through the counsels of his attendant angel Raphael, to render him innocuous. By placing a fish's heart and liver on red-hot cinders, Tobias produces a smoky vapour that causes the demon to flee to Egypt, where Raphael binds him (Tobit 8:2-3).>>
