Glycolaldehyde And Ethanol Toward The L1157 Outflow: Resolved Images And Constraints On Glycolaldehyde Formation
Two main formation routes have been proposed for interstellar complex organic molecules (iCOMs): on dust grain surfaces and in the gas phase. Observing such molecules in protostellar outflow shock regions […]

Supercooling, Glass Formation, and Mineral Assemblages upon Freezing of Salty Ice Grains from Enceladus’s Ocean
The analysis of micrometer-sized ice grains emitted into space by Saturn’s moon Enceladus suggests that the moon’s subsurface ocean may be habitable. However, the formation conditions of these ice grains […]

Resolved Gas Temperatures and 12C/13C ratios in SVS13A from ALMA Observations of CH3CN and CH3-13-CN
Context. Multiple systems are common in field stars, and the frequency is found to be higher in early evolutionary stages. Thus, the study of young multiple systems during the embedded […]

Raiding Nature’s Genetic Toolbox For UV-C Resistance By Functional Metagenomics
As we assess the habitability of other worlds, we are limited by being able to only study terrestrial life adapted to terrestrial conditions.

Reflected Spectroscopy Of Small Exoplanets III: Probing The UV Band To Measure Biosignature Gasses
Direct-imaging observations of terrestrial exoplanets will enable their atmospheric characterization and habitability assessment. Considering the Earth, the key atmospheric signatures for the biosphere is O2 and the photochemical product O3.
