James Webb Space Telescope discovers 27 new Trans-Neptunian Objects, revealing unexpected Kuiper Belt composition.

Webb's deep images identified 27 new Trans-Neptunian Objects (TNOs), some as small as six miles wide, making this the most sensitive study of such worlds to date. Contrary to expectations that collisions would grind these bodies into dust, the new data show only a slight increase in small objects, suggesting the Kuiper Belt is not primarily composed of dust and crumbs.
