Image double en thermographie d'une partie de Jupiter.
Thermal images from ESO’s Very Large Telescope (VLT) and other ground-based telescopes show swirls of warmer air and cooler regions never seen before within Jupiter’s Great Red Spot. The images enable scientists to make the first detailed weather map of the inside of the giant storm system. One observation illustrated by this image is the correspondence between a warm core within an otherwise cold storm system and the reddest colour of the Great Red Spot. The image on the left was obtained with the VISIR on the VLT in Chile on 18 May 2008. It was taken in the infrared wavelength range of 10.8 microns, which is sensitive to Jupiter's atmospheric temperatures in the 300 to 600 millibar pressure range. That pressure range is close to the altitude of the white, red and brown aerosols seen in the visible-light image on the right, which was obtained by the NASA/ESA Hubble Space Telescope on 15 May 2008. These images show the interaction of three of Jupiter's largest storms — the Great Red Spot and two smaller storms nicknamed Oval BA and Little Red Spot.
