In love with a new image from yesterday’s work on the focused ion beam/scanning electron microscope! The sample center looks somewhat like a morel mushroom, with blobs of silicate in a network of iron-rich melt. A particularly cheerful blob can be found in the upper right corner of the region of interest.
