Viral Secrets From Glacial Ice Reveal Climate Adaptations
Researchers at The Ohio State University have made a significant discovery in understanding how viruses preserved in glacial ice have adapted to Earth’s climatic changes.

Impact of Ice Growth on the Physical and Chemical Properties of Dense Cloud Cores
We investigated the effect of time-dependent ice growth on dust grains on the opacity and hence on the dust temperature in a collapsing molecular cloud core, with the aim of […]

Ice Chemistry Modeling of Active Phase Comets: Hale-Bopp
We present a chemical kinetics model of the solid-phase chemical evolution of a comet, beginning with a long period of cold-storage in the Oort Cloud, followed by five orbits that […]

The Pre-perihelion Evolution of the Activity of Comet C/2017 K2 (PANSTARRS) During the Water Ice-line Crossover
Comets, relics from the early solar system, consist of dust and ice. The ice sublimates as comets approach the Sun, ejecting dust from their nuclei seen as activity. Different volatiles […]

Ice Planet Update: Mysterious Patterns Revealed Under An Antarctic Ice Shelf
An international research team deployed the uncrewed submersible ‘Ran’ underneath 350 m thick ice. They got back the very first detailed maps of the underside of a glacier, revealing clues […]
