The temperature‐dependent near‐infrared absorption spectrum of hexagonal H2O ice
TL;DR: In this article, the authors present the new absorption coefficient spectra along with an examination of the different temperature effects of hexagonal water ice at temperatures between 20 and 270 K, with thicknesses ranging from 100 μm to 1.0 cm.

Discovery of a Planetary-sized Object in the Scattered Kuiper Belt
TL;DR: In this article, the discovery and initial physical and dynamical characterization of the object 2003 UB313 was presented, which is a large Kuiper Belt object that is inclined by about 44° from the ecliptic.

TL;DR: In this paper, the analysis of near-infrared observations of the icy surface of Triton, recorded on 1995 September 7, with the cooled grating spectrometer CGS4 at the United Kingdom Infrared Telescope (Mauna Kea, HI), was performed in two steps.

TL;DR: Spectra from Cassini's Visual and Infrared Mapping Spectrometer reveal the presence of a vast tropospheric cloud on Titan and derived characteristics indicate that this cloud is composed of ethane and forms as a result of stratospheric subsidence and the particularly cool conditions near the moon's north pole.

TL;DR: Results from the occultation of the sun by Neptune imply a temperature of 750 � 150 kelvins in the upper levels of the atmosphere (composed mostly of atomic and molecular hydrogen) and define the distributions of methane, acetylene, and ethane at lower levels.

TL;DR: The near-infrared spectrum of Triton reveals ices of nitrogen, methane, carbon monoxide, and carbon dioxide, of which nitrogen is the dominant component, which challenges existing models of methane and nitrogen photochemistry on Tritons.
