Four and a half billion years ago, the forces that built our solar system were not gravity alone. MIT researchers, studying ancient grains locked inside an Antarctic meteorite, have found evidence that a powerful magnetic field — three to twelve times stronger than Earth's today — shaped the earliest moments of the solar nebula alongside gravity's pull. The discovery invites us to reconsider the origin story of our cosmic home, and perhaps of planetary systems everywhere.
