Mapping Extrasolar Planets

Mapping outside our solar system





Four views of the planet's cloudtops in infrared light, each centered at a point of longitude 90 degrees from the last. A grid of longitude lines is superimposed on the map. These views clearly show a hot spot that is offset from the substellar point (high noon) by about 30 degrees. The offset may indicate fast "jet stream" winds of up to 6,000 mph.
