Jupiter’s Great Red Spot in Motion

Winds within Jupiter’s Great Red Spot are simulated in this JunoCam view.


Winds within Jupiter’s Great Red Spot (GRS) are simulated in this JunoCam view that has been animated using models derived from velocity data collected by NASA’s Voyager spacecraft and Earth-based telescopes. It’s a 10-hour view of the GRS as if there was no day and night, with the animation resetting every 10 hours of simulated time. NASA’s Juno spacecraft acquired the original view during its passage over the GRS on July 10, 2017. Citizen scientists Gerald Eichstädt and Justin Cowart turned the JunoCam data into a colour mosaic. Then Juno scientists Shawn Ewald and Andrew Ingersoll applied the velocity data to the image to produce the looping animation. Courtesy NASA/JPL-Caltech/SwRI/MSSS/Gerald Eichstädt/Justin Cowart.
