  • Gliese 581c: Super-Earth Exoplanet
    The surface temperature, for example, would depend on the composition and thickness of the atmosphere. The atmosphere also determines how much light is reflected off the planet, and the magnitude of the greenhouse effect. The parent star of Gliese 581c ...

  • First Super-Earth Atmosphere Detected
    55 Cancri-e was once touted as one of the most exotic exo-planets ever discovered. Mass and radius modelling led some astronomers to speculate that its interior could be rich in carbon. And that much carbon crushed together under extreme pressure = diamonds.
