Scientists at the Lawrence Livermore National Laboratory have created aerogels made of diamonds. Aerogels are gels where the inner liquid has been replaced with a gas leaving a porous solid matrix that has a very low bulk density. To make the diamond aerogel, scientists constructed a carbon aerogel that was pumped full of neon gas and pressurized using a diamond anvil. Under high pressure, the Aerogel was heated using high-intensity lasers. The high heat and pressure simulated the conditions under which diamonds form naturally within the Earth. The resulting nanocrystalline diamond aerogel is strong, light, completely transparent, and biocompatible.
The large impact-scarred Huygens basin, known for its unusual elongated craters, is about 450 km in diameter and lies in the heavily cratered southern highlands. One of these odd craters, shown above, sits just to the south of the much larger Huygens basin. It is about 78 km in length, opens from just under 10 km wide at one end to 25 km at the other, and reaches a depth of 2 km.
