Giant Super-Earths Made Of Diamond Are PossibleSan Francisco CA (SPX) Dec 07, 2011 A planet made of diamonds may sound lovely, but you wouldn't want to live there. A new study suggests that some stars in the Milky Way could harbor "carbon super-Earths" - giant terrestrial planets that contain up to 50 percent diamond. But if they exist, those planets are likely devoid of life as we know it. The finding comes from a laboratory experiment at Ohio State University, where researchers recreated the temperatures and pressures of Earth's lower mantle to study how diamonds form there. ... read more |
