"Uncovering Neptune's Evolution with the James Webb Space Telescope"

Scientists have used the James Webb Space Telescope to analyze the surface compositions of a binary duo of icy asteroids, Mors-Somnus, for the first time, shedding light on the evolution of Neptune and other objects in the outer solar system. The study, part of the DiSCo-TNOs program, provides insights into the dynamical history of Neptune and trans-Neptunian objects, offering clues about Neptune's migration and settlement into its final orbit. The findings also contribute to our understanding of the formation and composition of small celestial bodies beyond Neptune, providing valuable information about the origins of the planets, moons, and small bodies in our solar system.
