A full-globe map of the "hot Jupiter" planet HD 189733b. The map reveals a "hot spot" that is offset from the substellar point (high noon) by about 30 degrees. The offset may indicate jet stream winds of up to 6,000 mph. Credit: NASA/JPL-Caltech/Heather Knutson (CfA) Source is http://www.cfa.harvard.edu/press/2007/pr200713_images.html.
