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.

Young Binary Star System May Form planets With Weird Orbits

Unlike our solitary Sun, most stars form in binary pairs -- two stars that orbit a common center of mass. Though remarkably plentiful, binaries pose a number of questions, including how and where planets form in such complex environments.
