Hubble and Webb Telescopes Reveal Surprising Shortage of Small Trans-Neptunian Objects

NASA scientists have for the first time combined the observational power of the Hubble and James Webb Space Telescopes to study Trans-Neptunian Objects, the distant bodies orbiting beyond Neptune. The joint effort allowed researchers to directly observe some of the smallest and faintest TNOs ever detected. Unexpectedly, the survey found fewer small TNOs than scientific models had predicted. The findings suggest these remote objects may retain a 'memory' of past conditions or collisional history in the outer solar system. The research marks a significant step in understanding the formation and evolution of the solar system's outermost regions.
