In a press release on the JPL/NASA site, researchers have announced that they have found water vapor in the atmosphere of HD 189733b. The star HD 189733 (HD 189733 A) is a yellow dwarf star (technically, a K dwarf, slightly smaller and cooler than our sun) about 63 light-years away in the constellation Vulpecula. The star can be found with binoculars 0.3 degrees east of the Dumbbell Nebula (M27). The planet is quite hot, over 1000 degrees C, and orbits its primary in just over two days. Star Stryder has a post on her blog filling in some more of the details.
