from RT.com: Carbon-rich planets containing big deposits of diamonds and graphite could turn out to be more common than previously thought, Yale astronomers discovered. The findings trigger a debate on how the carbon environments impact climate, geology and life. “Despite the relatively small amount of carbon on Earth, carbon has been critical for the emergence of life and the regulation of our climate through the carbon-silicate cycle,” Yale doctoral candidate, John Moriarty, told YaleNews. “It’s an open question as to how carbon-rich chemistry will affect the habitability of exoplanets. We hope our findings will spark interest in research to help answer these questions,” Moriarty added.
