This SEM image shows a polished thin section of Asuka 12236. The section is about 1 cm (a third of an inch) across. Most of the bright grains in the image are iron-nickel-metal and/or iron-sulfide. The gray is mostly silicate, with the darker gray areas more magnesium-rich, while the lighter gray areas are more iron-rich. The roundish objects, and some fragments of them, that tend to contain most of the small, bright metal grains are called chondrules, which formed as molten droplets. They are set in a very fine-grained matrix, which is where the organic compounds and presolar grains are found. Image credit: Carnegie Institution for Science / Conel M. O’D. Alexander.
