The detection of atomic oxygen emission from Europa is reported, which is interpreted as being produced by the simultaneous dissociation and excitation of atmospheric O2 by electrons from Jupiter's magnetosphere.
Transient Water Vapor at Europa’s South Pole
Europa's Plumes Jupiter's moon Europa has a subsurface ocean and a relatively young icy surface, and spectral images taken by the Hubble Space Telescope show ultraviolet emissions from the moon's atmosphere that are consistent with two 200-km-high plumes of water vapor.
Interaction of the Jovian magnetosphere with Europa: Constraints on the neutral atmosphere

Abstract Thirteen lines of the CO band near 4.7 μm have been observed on a jovian hot spot at a resolution of 0.045 cm−1. The measured line profiles indicate that the CO mole fraction is 1.0±0.2 ppb…
The Pluto system: Initial results from its exploration by New Horizons

- 16 October 2015
The New Horizons encounter revealed that Pluto displays a surprisingly wide variety of geological landforms, including those resulting from glaciological and surface-atmosphere interactions as well as impact, tectonic, possible cryovolcanic, and mass-wasting processes.
