James Webb and Hubble Telescopes Reveal Ancient, Unchanged Icy Worlds in Outer Solar System

New observations from NASA's James Webb Space Telescope and Hubble Space Telescope have provided the most extensive census to date of tiny, icy worlds in the Kuiper Belt, revealing that these small bodies have remained largely unchanged since the early formation of the solar system. This discovery, detailed in two studies in The Astronomical Journal, offers crucial insights into the building blocks of planets.
