Water-rich atmosphere of super-earth 40 light-years away discovered

The astronomers and planetary scientists has used Subaru Telescope’s two optical cameras, Suprime-Cam and the Faint Object Camera and Spectrograph (FOCAS), with a blue transmission filter to observe planetary transits of super-Earth GJ 1214 b (Gliese 1214 b).

The team investigated whether this planet has an atmosphere rich in water or hydrogen.

The Subaru 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.

GJ 1214 b is located in the constellation Ophiuchus, northwest of the center of our Milky Way galaxy.

This planet is one of the well-known super-Earths discovered by Charbonneau et. al. (2009) in the MEarth Project, which focuses on finding habitable planets around nearby small stars. (ANI)
