When viewed under a microscope, a meteorite reveals a fascinating microcosm of the cosmos, characterized by a mix of minerals and textures that tell a story of its journey through space. The most striking features are the chondrules—spherical grains formed in the early solar system, often composed of silicate minerals like olivine and pyroxene. These chondrules are set within a fine-grained matrix that may include metallic iron-nickel and sulfide minerals.

In some meteorites, especially iron meteorites, the Widmanstätten pattern can be observed, displaying a distinctive interlocking crystal structure of iron-nickel alloys, formed over millions of years of slow cooling in space. The overall composition, ranging from crystalline to amorphous regions, along with occasional inclusions of tiny diamonds or other exotic minerals, provides a window into the early solar system's processes and the formation of planets.
