Detection Of Phosphorus-bearing Molecules Towards A Solar-type Protostar
Phosphorus is a key ingredient in terrestrial biochemistry, but is rarely observed in the molecular ISM and therefore little is known about how it is inherited during the star and […]

The HH 212 Interstellar Laboratory: Astrochemistry As A Tool To Reveal Protostellar Disks On Solar System Scales Around A Rising Sun
The investigation of star forming regions have enormously benefited from the recent advent of the ALMA interferometer. More specifically, the unprecedented combination of high-sensitivity and high-angular resolution provided by ALMA […]

Did Comet Impacts Jump-start Life On Earth?
Comets screaming through the atmosphere of early Earth at tens of thousands of miles per hour likely contained measurable amounts of protein-forming amino acids. Upon impact, these amino acids self-assembled […]

Unidentified Infrared Emission Features in Mid-infrared Spectrum of Comet 21P/Giacobini-Zinner
Comet 21P/Giacobini-Zinner (hereafter, comet 21P/G-Z) is a Jupiter-family comet and a parent comet of the October Draconids meteor shower. If meteoroids originating from a Jupiter-family comet contain complex organic molecules, […]

A Three-phase Approach To Grain Surface Chemistry In Protoplanetary Disks: Gas, ice Surfaces And Ice Mantles Of Dust Grains
We study the effects of grain surface reactions on the chemistry of protoplanetary disks where gas, ice surface layers and icy mantles of dust grains are considered as three distinct […]

Reactivity of HCO with CH3 and NH2 on Water Ice Surfaces. A Comprehensive Accurate Quantum Chemistry Study
Interstellar complex organic molecules (iCOMs) can be loosely defined as chemical compounds with at least six atoms in which at least one is carbon. The observations of iCOMs in star-forming […]

Life's Building Blocks mMy Have Formed In Interstellar Clouds
An experiment shows that one of the basic units of life — nucleobases — could have originated within giant gas clouds interspersed between the stars. Essential building blocks of DNA […]
