What object is shown in this zoomed-in close-up photo?

FeldsparGhost · Accepted Answer

Meteorite surface (macro). When meteorites crash through Earth's atmosphere, the extreme heat doesn't just melt their outer layer—it actually creates a shiny, glassy coating called a fusion crust that's usually only a millimeter thick, making it one of the easiest ways to spot a fresh meteorite in the field. Even cooler, this dark, glossy skin is often one of the first things to weather away, so meteorites that have been sitting on Earth for more than a few years tend to lose their telltale space-rock shine.
