Explanation: Jupiter looks a bit different in ultraviolet light. To better interpret Jupiter's cloud motions and to help NASA's robotic Juno spacecraft understand the planetary context of the small fields that it sees, the Hubble Space Telescope was being directed to regularly image the entire Jovian giant. The colors of Jupiter being monitored go beyond the normal human visual range to include both ultraviolet and (not pictured) infrared light. Featured from 2017, Jupiter appears different in near ultraviolet light, partly because the amount of sunlight reflected back is distinct, giving differing cloud heights and latitudes discrepant brightnesses. In the near UV, Jupiter's poles appear relatively dark, as does its Great Red Spot and a smaller (optically) white oval to the right. The String of Pearl storms farther to the right, however, are brightest in near ultraviolet, and so here appear (false-color) pink. Jupiter's largest moon Ganymede appears on the upper left. Juno continues on a looping 33-day orbit around Jupiter, while Earth-orbiting Hubble is aging and now relies on a single stabilizing gyroscope.

Pinging the APOD list
🪐 🌟 🌌 🍔
Tomorrow will be the last of the APOD posts that were delayed due to the government shutdown.
The Date should have been 11 Nov, 2025. My mistake. November 12 is the last post that was delayed by the government shutdown. Postings will resume at one per day after tomorrow.
Dang.
Watch you got.
I lost that one to Danny Smith in a game of marbles.
Is that a yarmulke? Is Jupiter really Jewpiter?
