An article published in the magazine “The Astronomical Journal” describes a research on the exoplanet 55 Cancri e. This super-Earth is one of the most studied among the planets in other solar systems but its extreme characteristics and the often experimental nature of the studies carried out provided partial and sometimes contradictory results. Now a analysis of data gathered using NASA’s Spitzer Space Telescope convinced a team of researchers that 55 Cancri e has an atmosphere and could have a composition similar to that of the Earth.
