Composite color infrared image of Jupiter (left) reveals haze particles over a range of altitudes, as seen in reflected sunlight. The image, consisting of 5 bands, used the Gemini North telescope with the Near-InfraRed Imager (NIRI) on May 18, 2017, one day before the Juno mission’s sixth close passage (“perijove”) of the planet. At longer infrared wavelengths (right), Jupiter glows with thermal emission at 4.8-micron image. This image, obtained with the Gemini North telescope’s Near-InfraRed Imager (NIRI), was obtained on January 11, 2017, so the relative positions of discrete features have changed with respect to the near-infrared image at left.
