Synthesis Of Mineral-organic Hybrid Materials Under Dynamic Prebiotic Conditions
[Nature] The increasing of molecular complexity must be understood as a planetary phenomenon where prebiotic chemistry and geological settings converge. In this scene, HCN chemistry may have played a crucial […]
![Proposed reaction network for the radiolysis of PCN:N2 ice by 40 MeV 40Ar9+ ions at 10 K. The scheme summarizes the main fragmentation, radical recombination, isomerization, and nitrogen incorporation pathways inferred from the infrared identifications and kinetic analysis. The radicals shown in the "Primary fragmentation" box are representative examples of how reactive intermediates are inferred from the experimental results and do not constitute an exhaustive list of all fragments produced during irradiation. -- [astro-ph.EP]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/08/Formation.png?resize=1200%2C706&ssl=1)

Formation Of Nitriles And Isonitriles By The Heavy-ion Irradiation Of Propionitrile In N2-rich Astrophysical Ices
[astro-ph.EP] Context. Nitriles are key nitrogen-bearing organic molecules in dense clouds, star-forming regions, and nitrogen-rich icy environments. Understanding their stability and chemical evolution under energetic processing is essential for understanding […]
![Computed abundance maps of ammonium cyanate, ammonium formate, ammonium acetate, ammonium hydrosulfide and ammonium carbamate in the solid phase for r < 50 au and computed after 1 Myr and 10 Myrs. We also show the ratio of the vertically integrated abundances of these salts relative to water ice. -- [astro-ph.EP]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/08/Ammonium-salt-.png?resize=1200%2C720&ssl=1)

Ammonium Salt Formation And Abundance In Protoplanetary Disks
[astro-ph.EP] Ammonium salts may represent an important reservoir of volatile species in Solar system primitive bodies, but the question of how and when these salts can form during the star […]

Key To Researching Large Planets: Research Team Discovers Novel Form Of Water
Temperatures of several thousand degrees Celsius and pressures of millions of atmospheres: superionic water only forms under extreme conditions. These conditions transform water into an unusual state in which hydrogen […]
