A team of scientists using NASA's Hubble Space Telescope has made the most detailed global map yet of the glow from a turbulent planet outside our solar system, revealing its secrets of air temperatures and water vapor.
Hubble observations show the exoplanet, called WASP-43b, is no place to call home. It is a world of extremes, where seething winds howl at the speed of sound from a 3,000-degree-Fahrenheit "day" side, hot enough to melt steel, to a pitch-black "night" side with plunging temperatures below 1,000 degrees Fahrenheit.
