Astronomers discover a water-rich planet outside our solar system

The Subaru Telescope is equipped with two optical cameras.

A Japanese research team of astronomers and other planetary scientists have used the Subaru Telescope to determine whether the surface of a planet that scientists have deemed a “super Earth” is rich in hydrogen or water.

The telescope is equipped with two optical cameras, Suprime-Cam and the Faint Object Camera and Spectrograph (FOCAS), with a blue transmission filter that aided the scientists in their investigation. Super-Earth GJ 1214 b (Gilese 1214 b) did not present through the filter with the appearance that would have indicated its richness in hydrogen so after taking into consideration previous research, the scientists concluded that the planet was most likely water-rich.
