This image shows Jupiter in infrared "light" in August 2008. Radiation particles bombard Jupiter's atmosphere near the planet's poles, creating auroral light shows. The radiation also interacts with gases in the Jovian atmosphere, chemically altering them and forming a haze in Jupiter's stratosphere. The polar stratospheric haze appears blue in this false-color image.
