JWST Detects Unique Ice Composition on Interstellar Comet 3I/ATLAS

The James Webb Space Telescope has identified an unusual ice composition on interstellar comet 3I/ATLAS, differing from typical solar system comets. Observations show its water ice lacks two faint absorption marks, a pattern computer simulations link to tiny ice particles mixed with dust. This discovery, published in The Astrophysical Journal Letters, provides new insights into the formation and evolution of objects originating outside our stellar neighborhood.
