JWST, For The First Time, Detected Water Ice In The Planet-Forming Disk Of A Young (23-Myr-Old) Sun-Like Star, HD 181327, 155 Ly Away. Ice Was Found Concentrated In The Outer Disk, Like In Our Kuiper Belt. This Finding Supports Theories That Comets & Asteroids Brought Water To Inner Planets, As In Earth‘s Late Heavy Bombardment 4 Byrs Ago.
