Was Earth’s Water Acquired Locally During The Earliest Phases Of The Solar System Formation?
The origin of the terrestrial water remains debated, as standard Solar System formation models suggest that Earth formed from dry grains, inside the snowline of the Proto-Solar Nebula (PSN).

Glycolaldehyde Formation Mediated By Interstellar Amorphous Ice: A Computational Study
Glycolaldehyde (HOCH2CHO) is the most straightforward sugar detected in the Interstellar Medium (ISM) and participates in the formation pathways of molecules fundamental to life, red such as ribose and derivatives.
