Science Nonfiction Double Feature

Scientists are fairly certain that they've discovered water vapor on a planet some 63 light years away from earth. The planet goes by the name HD 189733b, and it's described as a "hot Jupiter." Like our own Jupiter, it's not a likely candidate for life. However, the detection itself represents significant progress toward being able to understand the subtleties of the worlds around (and beyond) us.In other precipitant news (from ABC), scientists "discovered extraordinarily precise data on rainfall in the Mediterranean region from 200 B.C. to 1100 A.D. which suggests that the fall of the Roman and Byzantine empires may have been partly caused by climate change."Meanwhile, back in the present, it's snowing in New Orleans.(Photo of HD 189733b via Wired News.)
