Jovian clouds strike unlikely shades of blue in this view from NASA’s Juno spacecraft.
Juno captured the image when the spacecraft was less that 19,000 kilometres from the tops of Jupiter’s clouds — that’s roughly as far as the distance between New York City and Perth, Australia. The color-enhanced image, which captures a cloud system in Jupiter’s northern hemisphere, was taken on October 24, 2017 when Juno was at a latitude of 57.57 degrees (nearly three-fifths of the way from Jupiter’s equator to its north pole) and performing its ninth close flyby of the gas giant planet.
The spatial scale in this image is 12.5 kilometres per pixel.
Because of the Juno-Jupiter-Sun angle when the spacecraft captured this image, the higher-altitude clouds can be seen casting shadows on their surroundings. The behavior is most easily observable in the whitest regions in the image, but also in a few isolated spots in both the bottom and right areas of the image.
Citizen scientists Gerald Eichstädt and Seán Doran processed this image using data from the JunoCam imager.
