First Map of Alien World

[koolbluez]

Data from the Spitzer Space Telescope has been used by researchers to make the first-ever map of an extrasolar planet. It's a weather map, more precisely. The map, which shows temperature variations across the cloudy tops of a gas giant called HD 189733b, is made up of infrared data taken by NASA's Spitzer Space Telescope. Hotter temperatures are represented in brighter colors.
