The trans-Neptunian objects (TNOs), along with the Oort cloud comets and the icy moons of the giant planets, constitute the primary reservoirs of ices in the Solar System. Decades of ground- and space-based observations of the icy Solar System, as well as NASA and ESA spacecraft exploration, have unveiled a myriad of molecular species. At the same time, ices play a pivotal role as carriers of volatiles in protoplanetary disks, crucial for understanding the chemistry that ultimately dictates the organic composition of planets. Disk snowlines are pivotal in shaping the compositions of Solar System planets, moons, and small bodies.
The distribution of CHONS ices during the planetary formation in protoplanetary disks leaves a footprint in the composition of ice bodies. However, despite being a focal point of interest since the discovery of Albion in 1992, ices had remained elusive for decades, but not anymore!.
We are embarking on a new era in the study of ices in the Solar System, exoplanets, and disks, thanks to the advanced instrumentation aboard the James Webb Space Telescope. In this presentation, I will discuss some of the initial findings from various Webb observing programs ranging from small, red, cold classical bodies akin to Arrokoth, to the large dwarf planets, Eris, Makemake, and Pluto, ice giants with a warm heart. Hopefully, this presentation will catalyze discussions on how compositional characterization of small bodies in the NIR spectrum could naturally deep the understanding of the icy ingredients in planetary systems.
