"We predict that ionic or plasma water can be seen deep inside the planet," Narita said. "However, we may not be able to find hot 'ice' - high pressure-ices - inside of Gliese 1214 b."
Originally discovered in by the MEarth Project, which tracks more than 2,000 low-mass stars in search of planets, Gliese 1214 b was confirmed by the European Space Agency's High Accuracy Radial velocity Planet Searcher in Chile.
As a planet travels across the face of its star, or transits, it blocks the star's light slightly, allowing scientists to determine characteristics about it based on how much the light dims.
Though water is often considered a necessary ingredient for life by scientists, Narita doesn't think that the super-Earth will be promising due to its close orbit, which lies within the star's habitable zone, the region where liquid water can exist.
"Although water vapor can exist in the atmosphere, liquid water - namely oceans - would not exist on the surface of this planet," he said. "So unfortunately, we do not think this planet would be habitable."
