First Detection of Super-Earth Atmosphere

For the first time astronomers were able to analyse the atmosphere of an exoplanet in the class known as super-Earths. Using data gathered with the NASA/ESA Hubble Space Telescope and new analysis techniques, the exoplanet 55 Cancri e is revealed to have a dry atmosphere without any indications of water vapour. The results, to be published in the Astrophysical Journal, indicate that the atmosphere consists mainly of hydrogen and helium.

Due to its proximity to its parent star, the temperatures on the surface of the planet are thought to reach about 2000 degrees Celsius. Scientists were able to analyze the atmosphere of 55 Cancri e. It was the first time this was possible for a super-Earth exoplanet.
