Scientists think there's a 10-mile-thick layer of diamond beneath the surface of Mercury, which would make you around 876 billion Minecraft pickaxes if my math is right
Mercury is nobody's favorite planet. Our star's closest companion is a hateful little ball pocked with craters and patches of graphite, continually blasted by solar wind. But according to a recent study from a team of Chinese and Belgian scientists (via Space.com), there are diamonds under all that rough. A 10-mile-thick layer of diamond, to be specific.
