Local Constraints On Alcohol–Thioalcohol Analogs In G35.2N
[astro-ph.GA] The chemistry of sulfur-bearing complex organic molecules in dense star-forming environments remains uncertain, partly because the dominant sulfur reservoirs in dense gas and ices are poorly identified. Alcohol–thioalcohol pairs […]

Glycine In The Interstellar Medium Revisited: Resolving Conformational Complexity Kinetically
[astro-ph.GA] Numerous attempts to detect glycine, a simple amino acid and a key building block of proteins in all life on Earth, in the interstellar medium have so far been […]
![Binding energies of CO, CO2 and NH3 on pristine and cavity-containing ice clusters consisting of 100 and 97 H2O molecules, respectively. The error bars represent the spread in adsorption energies across the three clusters.

Spectral Evolution Of Ceres’ Surface and Implications For Space Weathering
[astro-ph.EP] The surface of Ceres exposed to the space environment will be gradually altered, but the evolution of its spectral properties remains poorly understood. Here we analyze visible and infrared […]

Chemists Uncover How Unthinkable Reactions Occur In Unimaginable Conditions
[Florida International University] Before there was Earth, there was chemistry. In the unimaginable cold, dark clouds where stars and planets are born, carbon molecules assemble into more complex forms — […]
![Temporal evolution of selected species and D/H ratios during the cloud (top panels) and core stages (lower panels). Panels (a) and (e) show the abundances of selected species during the cloud and core stages, respectively. Solid, dashed, and dotted lines denote models with Z = 1, 0.5, and 0.2, respectively. The remaining panels show the temporal evolution of the D/H ratios and the H2 OPR for Z = 1 (b, f), Z = 0.5 (c, g), and Z = 0.2 (d, h). In all panels, time is normalized by τfreeze for the corresponding density and metallicity. -- [astro-ph.EP]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/09/High-water.png?resize=1200%2C719&ssl=1)

High Water D/H Ratio of the Interstellar object 3I/ATLAS is Consistent With a Low-metallicity Origin
[astro-ph.EP] Recent JWST observations have revealed unusually high 12C/13C ratios in carbon-bearing molecules of the interstellar object 3I/ATLAS, consistent with formation in a lower-metallicity environment than the present-day local interstellar […]

OSIRIS-REx Returned a Pristine Sample of Asteroid Bennu: Takeaways from the Mission’s Contamination Control and Knowledge Program
[astro-ph.EP] NASA’s OSIRIS-REx mission had the objective of delivering a pristine sample from asteroid (101955) Bennu to Earth for scientific analysis–where “pristine” signifies the absence of foreign materials that could […]
