Astronomy & Astrophysics, 2006 Aims. We investigate the surface composition of Centaurs and Trans-Neptunian objects (TNOs) to get constraints on the formation and the evolution of this population. Methods. We report visible and near-infrared spectroscopic observations of the Plutino 55638 (2002 VE 5 ) obtained at VLT-ESO.

ICES Report on Ocean Climate 2019 [PDF]
, 2020 Long time-series of ocean properties are rare in the surface ocean and even more uncommon in the deep ocean. The North Atlantic region is unique, having a relatively large number of locations where oceanographic data have been collected repeatedly for ...

A CO2 Cycle on Ariel? Radiolytic Production and Migration to Low-latitude Cold Traps
The Planetary Science Journal, 2022 CO _2 ice is present on the trailing hemisphere of Ariel but is mostly absent from its leading hemisphere. The leading/trailing hemispherical asymmetry in the distribution of CO _2 ice is consistent with radiolytic production of CO _2 , formed by charged

Microbial abundance in surface ice on the Greenland Ice Sheet [PDF]
Frontiers in Microbiology, 2015 Measuring microbial abundance in glacier ice and identifying its controls is essential for a better understanding and quantification of biogeochemical processes in glacial ecosystems. However, cell enumeration of glacier ice samples is challenging due to typically low cell numbers and the presence of interfering mineral particles. We quantified for the

GEOLOGICAL MAPPING OF PLUTO AND CHARON USING NEW HORIZONS DATA [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016 Pluto and Charon exhibit strikingly different surface appearances, despite their similar densities and presumed bulk compositions. Systematic mapping has revealed that much of Pluto’s surface can be attributed to surface-atmosphere interactions and the ...

Crystallization Kinetics of Vitreous Magnesium Sulfate Hydrate and Implications for Europa’s Surface
The Planetary Science Journal, 2023 Brines consistent with that expected for Europa’s global subsurface ocean have been shown to form vitreous salt hydrates when frozen. We report experiments examining the crystallization kinetics of vitreous MgSO _4 hydrate in order to better understand ...

Closer look at the surface of ice [PDF]
Proceedings of the National Academy of Sciences, 2016 When hydrogen bonds are broken at an interface, water molecules are forced to adopt configurations that are not as energetically favorable as those deep within the bulk of the material. At the interface between ice and its vapor, this can result in the top layers of ice becoming disordered.
