Blue light observations indicate water-rich atmosphere of super-Earth

more »

Astronomers and planetary scientists have observed planetary transits of super-Earth GJ 1214 b (Gilese 1214 b). The team investigated whether this planet has an atmosphere rich in water or hydrogen. The observations show that the sky of this planet does not show a strong Rayleigh scattering feature, which a cloudless hydrogen-dominated atmosphere would predict. When combined with the findings of previous observations in other colors, this new observational result implies that GJ 1214 b is likely to have a water-rich atmosphere.
