How did the first solids that made up planets, moons and asteroids form from the "hot soup" that characterized our solar system's earliest years? New research from Caltech analyzing pieces of a meteorite has found that, just as snowflakes crystallize around grains of dust, ancient stardust grains left over from long-gone suns may have been the seeds of our solar system's earliest solids.
