Mercury has an 11-mile thick diamond layer between its core and mantle
A recent study published in Nature Communications suggests that Mercury, the smallest planet in the solar system, has a thick diamond layer at its core-mantle boundary, up to 18 kilometers (11 miles) thick. This finding, from scientists in China and Belgium, challenges previous assumptions that graphite was the only stable form of carbon on Mercury. The diamond layer likely formed from the crystallization of Mercury’s carbon-rich magma … Continue reading Mercury has an 11-mile thick diamond layer between its core and mantle
