A temperature map of HD 189733b reveals a warm spot on its "sunlit" side, which is always pointed toward the star. But the map also shows that this spot is offset from the high-noon point by 30 degrees. According to scientists, ferocious winds traveling up to 6,000 miles per hour are probably pushing the hot spot to the east. Credit: NASA/JPL-Caltech/Harvard-Smithsonian CfA
