This material was a bead of molten silicate, floating in space 4.65 billion years ago. Upon solidification, the perfect sphere became among the first solid materials in the solar system and was incorporated into a rock, which experienced little modification until it fell to Earth somewhat recently, landing in Antarctica. It was collected by NASA and confirmed to be a CV3-class carbonaceous chondrite. This type of meteorite has a bulk composition close to that of the sun, and is thought to represent the building blocks of planets like Earth.
