Observations indicate that the total abundance of S-bearing species in dense clouds is orders of magnitude lower than the cosmic sulfur abundance.
Recent observations of protostars with the James Webb Space Telescope have revealed unprecedented chemical complexity from their ice absorption features.
Understanding how to explore hidden glaciers on Mars begins not in a laboratory, but in remote field camps across Alaska and Wyoming.
Nitrogen-bearing molecules are more difficult to observe than oxygen-bearing ones, mainly due to the lower abundance of nitrogen in the interstellar medium.
The geophysical evolution and astrobiological potential of ocean worlds are indelibly linked to the chemical compositions of their oceans and ice shells.
Coordinating with the CaSSIS instrument on the ExoMars Trace Gas Orbiter, we acquired an image at this site for seasonal monitoring.
Complex organic molecules (COMs) are thought to form in cold interstellar environments, yet the chemical routes to key prebiotic precursors remain poorly understood. Glycine, the simplest amino acid, has not […]
The icy material within protoplanetary disks plays a central role in planet formation, yet remains poorly characterized by observations. We present 1.6-28μm spectra of five disks obtained as part of […]
Using JWST/MIRI observations, we report the detection of CO2 ice in the dusty torus of the planetary nebula NGC 6302, an environment generally considered hostile to fragile molecular species and […]
The chemical evolution in star forming regions is driven by the interplay between gas and ice mantles. Identifying the ice compositions at the early stage of star formation thus provides […]
