Astronomers have discovered possible atmospheric gases on 55 Cancri e, a hot rocky exoplanet at 41 light years from Earth. This is the best evidence yet for an atmosphere around a rocky planet outside our solar system. Gas bubbling up from a lava-covered surface possibly feeds an atmosphere rich in carbon dioxide or carbon monoxide. The researchers, including astronomers from SRON and Leiden Observatory, publish their findings in Nature.
