Original Caption Released with Image:

This false-color image of Jupiter was taken on May 18, 2017, with a mid-infrared filter centered at a wavelength of 8.8 microns, at the Subaru Telescope in Hawaii, in collaboration with observations of Jupiter by NASA's Juno mission.

The selected wavelength is sensitive to Jupiter's tropospheric temperatures and the thickness of a cloud near the condensation level of ammonia gas. The Great Red Spot appears distinctively at the lower center of the planet as a cold region with a thick cloud layer. It is surrounded by a warm and relatively clear periphery. To its northwest is a turbulent and chaotic region where bands of gas that is warm and dry alternate with bands of gas that is cold and moist.

This image, taken a few hours before Juno's sixth close approach to Jupiter, shows the detailed atmospheric structure of the Great Red Spot and its surroundings that the Juno mission will encounter on its seventh closest approach to Jupiter on July 10, 2017, Pacific Time (July 11, Universal Time).

The instrument used to take this image is Cooled Mid-Infrared Camera and Spectrometer (COMICS) of the National Astronomical Observatory of Japan's Subaru Telescope on Hawaii's Maunakea peak.

An image of Jupiter taken the same night as this one, from a nearby telescope but at shorter infrared wavelengths, is at PIA21713.

NASA's Jet Propulsion Laboratory manages the Juno mission for the principal investigator, Scott Bolton, of Southwest Research Institute in San Antonio. Juno is part of NASA's New Frontiers Program, which is managed at NASA's Marshall Space Flight Center in Huntsville, Alabama, for NASA's Science Mission Directorate. Lockheed Martin Space Systems, Denver, built the spacecraft. Caltech in Pasadena, California, manages JPL for NASA.
