These images are micrographs (photographs through a microscope) of chondrule formations from a meteorite fall known, simply,as NWA 5142 (Northwest Africa fall #5142) taken by Tom Phillips. A chondrule is a round grain found in certain types of meteoritesknown as chondrites. Chondrules form as molten or partially molten droplets in space before being accreted (gravitationally attached)to their parent asteroids. Chondrites represent the oldest solid material within our solar system and are believed to be the buildingblocks of our planetary system.
