Subj : Daily APOD Report To : All From : Ben Ritchey Date : Tue Oct 16 2018 10:33:23 Astronomy Picture of the Day Astronomy Picture of the Day Discover the cosmos! [1] Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2018 October 16 [2] Jupiter in Ultraviolet from Hubble Image Credit: NASA [3] , ESA [4] , Hubble [5] ; Processing & License [6] : Judy Schmidt [7] Explanation: Jupiter looks a bit different in ultraviolet light. To better interpret Jupiter [8] 's cloud motions and to help NASA's robotic Juno [9] spacecraft understand the planetary context [10] of the small fields that it sees, the Hubble Space Telescope [11] is being directed to regularly image [12] the entire Jovian giant. The colors of Jupiter being monitored [13] go beyond the normal human visual range to include both ultraviolet [14] and infrared [15] light. Featured [16] 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 [17] . In the near UV, Jupiter [18] 's poles appear relatively dark, as does its Great Red Spot [19] and a smaller (optically) white oval [20] to the right. The String of Pearl [21] storms farther to the right, however, are brightest in near ultraviolet, and so here appear (false-color) pink. Jupiter's largest moon Ganymede [22] appears on the upper left. Juno [23] continues on its looping 53-day orbits around Jupiter, while Earth-orbiting Hubble is now recovering [24] from the loss of a stabilizing gyroscope [25] .
