Waspie_Dwarf Posted April 14, 2015 #1 Share Posted April 14, 2015 Hot and Stormy at High Altitudes on Exoplanet HD 189733b Studying the atmosphere of an exoplanet, Swiss astronomers derived a temperature profile with unprecedented precision. Their results are based on data collected with a relatively small ground-based telescope. This opens completely new perspectives for the characterization of remote exoplanetary atmospheres.It is several thousand degrees hot, high up in the atmosphere of the exoplanet named HD 189733b, a gas-giant located 63 light-years away from Earth in the constellation Vulpecula (the "little fox"). The temperature is increasing with altitude and reaches more than 3,000 degrees Celsius, enough to melt iron and much in excess of the planet's equilibrium temperature. Read more...
