Oxygen-bearing Organic Molecules In Comet 67P’s Dusty Coma: First Evidence For Abundant Heterocycles
The puzzling complexity of terrestrial biomolecules is driving the search for complex organic molecules in the Interstellar Medium (ISM) and serves as a motivation for many in situ studies of […]

The Effects Of Atmospheric Entry Heating On Organic Matter In Interplanetary Dust Particles
Interplanetary dust particles (IDPs) were likely major sources of extraterrestrial organics to the early Earth. However, IDPs experience heating to > 500 °C for up to several seconds during atmospheric […]
