Summary: By analyzing ALMA archive data, the study detected the submillimeter spectrum of SO2 gas from volcanic plumes and lava areas on Jupiter's moon Io, with high intensity areas of SO2 found to be associated with volcanically active regions. Column densities and temperature changes before and after eclipse suggest volcanic eruptions maintain the atmosphere, while atmospheric SO2 around Janus Patera may be supplied by evaporation from lava areas after eclipse.

Summary: Martian atmospheric neon can reflect the volatile content of the interior, with recent studies suggesting active volcanism on Mars and a much higher abundance of neon in the mantle compared to Earth. These findings provide important constraints on the abundance of other volatile elements in Mars' interior and its accretion history.

Summary: This paper presents the extensive verification of the S5P SO2 layer height (S5P+I: SO2LH) product over major recent volcanic eruptions, as well as assesses its impact on volcanic forecasts. The results show good agreement between the S5P and IASI observations, and the assimilation of the S5P SO2 LH product improves model output and the geographical spread of volcanic plumes.

Summary: This study compares the ability of different Martian reanalysis datasets to represent the growth and decay of short-period transient eddies. The results show that these eddies primarily occur in the Northern Hemisphere of Mars and grow on the upstream sides of basins. The overall effect of barotropic energy conversion is a net loss of eddy kinetic energy. When using data from the Thermal Emission Spectrometer, the reanalysis results agree on the amplitude and timing of the eddies, but there is less constraint during the Mars Climate Sounder observational era. The analysis of individual eddies during this era should only be performed when there is agreement across reanalyses and large eddy amplitudes.

Summary: Studying geothermal pools in Iceland reveals that volcanic processes play a significant role in controlling the geochemistry and microbial community structure. The pools in Kerlingarfjoll and Kverkfjoll exhibit different water chemistry, sediment composition, and dominant microbial metabolisms, influenced by volcanic processes and water input from glaciers. This research provides insights into the potential habitability of relic hydrothermal systems on Mars and their significance in supporting chemolithotrophic life.

Summary: The NASA Applied Sciences Disasters Program aims to expedite the processing and delivery of volcanic ash and sulfur dioxide satellite data through collaboration and technological development. The development of low-latency quantitative retrievals of SO2 column density and thermal infrared SO2 and ash indices addresses critical needs for nighttime coverage over the northern polar regions. The data produced within 30 minutes of satellite overpasses are distributed to relevant observatories and centers, with the software packages available for a global user community.

Summary: We present six years of temperature observations of Mars' middle and upper atmospheres during the day, obtained using the Imaging Ultraviolet Spectrograph instrument aboard the MAVEN spacecraft. Our results reveal strong long-term variability in thermospheric temperatures, which is linked to Martian seasons and the solar cycle. Both the thermosphere and mesosphere exhibit pronounced short-term variations, indicating a coupling with the lower atmosphere. Additionally, we identify a significant local time effect, with the thermosphere being colder in the morning and warmer in the evening.

Summary: Efforts to detect methane in the Martian atmosphere have been hindered by dust interference, leading to upper limits on methane detections. While the absence of methane in TGO spectra contradicts previous detections by Curiosity, it also strengthens constraints on the mechanism explaining lower methane abundances.

Summary: This article presents an analysis of a recent submarine eruption of the Hunga Tonga-Hunga Ha'apai volcano in Tonga, using ultraviolet satellite measurements. The study estimates the sulfur dioxide emissions of this eruption to be approximately 0.6-0.7 Tg SO2, which is relatively low compared to other eruptions of similar magnitude. The authors suggest that the reduced SO2 emissions may be attributed to the presence of water.

Summary: This study focuses on the systematic experimental determination of parameters related to cosmic-ray-induced sputtering in astrophysical environments. The research finds that ice sputtering yields are constant for thick films, but decrease rapidly for thin ice films. The thickness dependence constraint of ice mantles can be implemented in astrophysical modeling of the sputtering process.

Summary: This article focuses on the recent technological developments of atomic force microscopy-infrared (AFM-IR) technique. AFM-IR combines the high spatial resolution of atomic force microscopy with the chemical identification capability of infrared spectroscopy to achieve submicrometric physico-chemical analyses. Technological improvements have significantly advanced the capabilities of AFM-IR in terms of spatial and spectral resolution, sensitivity, and fields of applications. The paper provides an overview of these developments and ongoing limitations, as well as introducing new trends in AFM-IR implementation.

Summary: This study assesses the potential of oxygenated carbon chain ions as explanations for diffuse interstellar bands using density-functional theory and coupled cluster single-double and perturbative triple theory. The results show that the linear structures of these ions are the most stable and their optical absorptions mainly occur in the visible or near-infrared spectral regions. However, based on the known data, the growth rate of O-bearing carbon chains via ion-neutral reaction mechanisms is too low to account for the diffuse interstellar bands.

Summary: Massive stars disrupt the molecular cloud material through radiative and mechanical feedback processes, impacting the evolution of interstellar matter. Observations of Photo-Dissociation Regions (PDRs) provide insights into physical and chemical processes in interstellar and circumstellar media. PDR emission dominates infrared spectra of star-forming galaxies and will be a focus of observations with the James Webb Space Telescope (JWST).

Summary: This study explores the effect of grain growth on the spectroscopic profiles of ice mantle constituents, focusing particularly on carbon dioxide. The results show that the profile of carbon dioxide can serve as an indicator of grain growth, and observations have already shown signs of moderate grain growth. Future observations of protoplanetary disks with high inclination using the James Webb Space Telescope can provide constraints on the extent of dust growth.

The authors used a compendium of existing data on electronic sputtering to calculate the prefactors leading to the generalization of the stopping-power-dependent sputtering yield for many species. They also presented new experimental results to constrain the yield for specific molecules.

Summary: The study investigates the recurrent fluorescence of carbon clusters induced by stellar photon absorption and its ability to explain the near-IR emission observed in reflection nebulae and planetary nebulae. The modelling results suggest that C-60 cages and flakes, as well as C-42 cages, can account for the observed continuum emission. The carriers contain about 0.1-1.5% of the interstellar carbon abundance.

Summary: Icy grain mantles in interstellar clouds are important reservoirs of volatile elements that connect chemical processes with planet formation and atmospheric composition. Results from the Ice Age program using the James Webb Space Telescope reveal the rich composition of these dense cloud ices, showing the detection of weak ice features and complex organic molecules. The study suggests that simple and complex molecules can form early in ice-rich environments and JWST can trace the molecules seen in planetary atmospheres back to their origins in interstellar clouds.
