An unidentified absorption feature at 5.11 m on the surface of Titan and Pluto from JWST spectroscopy

B. Bézard, E. Lellouch, M. Camarca +14

Titan possesses a thick N-CH atmosphere that makes it difficult to study its surface spectroscopically. The chemical composition of the solid surface of Titan thus remains…

JWST reveals anomalously enhanced methane outgassing from below Chiron's water ice and carbon dioxide bearing surface

Ian Wong, Silvia Protopapa, Aurélie Guilbert-Lepoutre +7

Centaurs are inward-scattered Kuiper belt objects, with some exhibiting comet-like activity. The physical mechanisms powering this activity remain poorly understood, with carbon mo…

Unveiling the ice and gas nature of active centaur (2060) Chiron using the James Webb Space Telescope

N. Pinilla-Alonso, J. Licandro, R. Brunetto +15

(2060) Chiron is a large centaur that has been reported active on multiple occasions including during aphelion passage. Studies of Chirons coma during active periods have resulted…

A Tale of 3 Dwarf Planets: Ices and Organics on Sedna, Gonggong, and Quaoar from JWST Spectroscopy

J. P. Emery, I. Wong, R. Brunetto +10

We observed Sedna, Gonggong, and Quaoar with the NIRSpec instrument on the James Webb Space Telescope (JWST). All three bodies were observed in the low-resolution prism mode at wav…

Moderate D/H Ratios in Methane Ice on Eris and Makemake as Evidence of Hydrothermal or Metamorphic Processes in Their Interiors: Geochemical Analysis

Christopher R. Glein, William M. Grundy, Jonathan I. Lunine +7

Dwarf planets Eris and Makemake have surfaces bearing methane ice of unknown origin. D/H ratios were recently determined from James Webb Space Telescope (JWST) observations of Eris…

The science case for spacecraft exploration of the Uranian satellites: Candidate ocean worlds in an ice giant system

Richard J. Cartwright, Chloe B. Beddingfield, Tom A. Nordheim +15

The 27 satellites of Uranus are enigmatic, with dark surfaces coated by material that could be rich in organics. Voyager 2 imaged the southern hemispheres of Uranus' five largest '…

The Science Case for Spacecraft Exploration of the Uranian Satellites

Richard J. Cartwright, Chloe B. Beddingfield, Tom Nordheim +14

The five classical Uranian moons are possible ocean worlds that exhibit bizarre geologic landforms, hinting at recent surface-interior communication. However, Uranus' classical moo…
