WebVisible inside most stone meteorites are tiny, glassy, spheres known as chondrules. Forged at the very dawn of the solar system, these chondrules are far older than our own planet. Some stone meteorites, known as carbonaceous chondrites, have been found to contain water, salt, and even amino acids. A chondrite /ˈkɒndraɪt/ is a stony (non-metallic) meteorite that has not been modified, by either melting or differentiation of the parent body. They are formed when various types of dust and small grains in the early Solar System accreted to form primitive asteroids. Some such bodies that are captured in the planet's gravity well become the most common type of meteorite by (whether quickly, o…
