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.
