Nanoscale Infrared Spectroscopy Reveals Complex Organic–mineral Assemblages In Asteroid Bennu

by Keith Cowing

Asteroid Bennu preserves primitive material from the early solar system, and returned samples allow direct examination of how organics and minerals were assembled and altered. We applied nanoscale infrared spectroscopy […]

Organosulfur Chemistry On sub-Neptunes: Implications For Hazes And Biosignatures

by Keith Cowing

The organosulfur biosignature gases dimethylsulfide (DMS) and dimethlydisulfide (DMDS) have recently been claimed to be present in the atmosphere of sub-Neptune exoplanet K2-18b, leading to the suggestion of possible extraterrestrial […]
