The astrobinary’s two subunits bear similar traces of partial destruction, except the faceted nanocrystals in the cores that are uniformly solid and smooth (Figure 3). (a) and (b) Volume-rendered images of the binary’s interior slicing through the grain cores (brighter), viewed at angles of about ±90° to Figure 3(a), respectively. Apparent zigzag-like outlines are due to uneven surfaces. Bright linear features that appear vertically and horizontally result from phase-contrast effects occurring at the edges of oriented nanoinclusions, as seen from Figure 3(e). The brightest spots correspond to portions of the larger nanocrystals. Volume: 47.25 × 173.25 × 425.25 nm³.
