Early Solar System Built First Worlds From Fire, Not Ice

In the earliest chapter of our Solar System's story, the first planetary building blocks were not assembled from the icy abundance scientists long imagined, but from heat-forged rock shaped by the young Sun itself. New research reveals that aerodynamic forces quietly sorted the raw materials of creation, concentrating rocky chondrules into the first planetesimals at rates as high as 92 percent. This discovery invites us to reconsider not just our own origins, but the universal physical laws that may govern how worlds are born across the cosmos.
