Strange Super-Earth Planet Has 'Plasma' Water Atmosphere
A nearby alien planet six times the size of Earth is covered with a water-rich atmosphere that includes a strange "plasma form" of water, scientists say. Astronomers have determined that the atmosphere of super-Earth Gliese 1214 b is likely water-rich. However, this exoplanet is no Earth twin. The high temperature and density of the planet give it an atmosphere that differs dramatically from Earth.
