We explore how researchers used barycentric free orbital elements to strip Neptune’s gravitational noise from 1,650 Kuiper Belt objects and fed the stable, free elements into DBSCAN. The result? A second, colder cluster—an inner kernel around 43 AU just inward from the known kernel near 44 AU—offering a pristine fossil record of the solar system’s birth. The finding tightens constraints on Neptune’s early migration and dynamical heating, and LSST/Rubin Observatory data should soon tell us whether the two structures are truly distinct or part of a single belt shape shaped by resonances. A showcase of how advanced data processing drives breakthroughs in astronomy and beyond.Note: This podcast was AI-generated, and sometimes AI can make mistakes.
