"This is a very exciting result because it's the first time that we have been able to find the spectral fingerprints that show the gases present in the atmosphere of a super-Earth," UCL PhD student Angelos Tsiaras said in a statement. "The observations of 55 Cancri e's atmosphere suggest that the planet has managed to cling on to a significant amount of hydrogen and helium from the nebula from which it originally formed."

Unfortunately, 55 Cancri e probably doesn't support life. Its atmosphere appears to be comprised almost entirely of hydrogen and helium with no traces of water. Plus, the planet is so close to its star that a year there lasts 18 Earth-hours and the surface of the planet can get as hot as 2,000 degrees C.
