(a) 1 mm continuum image of G358.93-0.03. Contour levels correspond to (20, 40, 80, 120, 200, 500, 1000, 1700) × σ, where σ is the rms noise level. The white ellipse in the lower-left corner indicates the synthesized beam 0.15"×0.1" (position angle -87.1◦ ). (b) Enlarged view of MM1. The continuum peak is marked by a white cross, and the offset extraction position used for spectral analysis is marked by a red cross. (c-e) Integrated intensity (Moment-0) maps of NH2CHO, CH3C(O)NH2, and syn-HOCH2C(O)NH2 toward G358.93 MM1, overlaid with 1 mm continuum emission contours from panel (a). The color scale unit is Jy beam−1 km s−1. -- astro-ph.GA

First Detection of the Glycine Isomer Glycolamide in Hot Molecular Core

by Keith CowingMarch 25, 2026March 25, 2026

Understanding whether prebiotic molecules can endure and reform through the energetic stages of star formation is essential for tracing the continuity of interstellar chemistry toward life. Glycolamide, an isomer of […]

Expanding the C3H6O2 Isomeric Interstellar Inventory: Discovery of Lactaldehyde and Methoxyacetaldehyde in G+0.693-0.027

by Keith CowingJanuary 17, 2026January 17, 2026

The tentative detection of 3-hydroxypropanal (HO(CH2)2C(O)H) toward the Galactic center molecular cloud G+0.693-0.027 prompts a systematic survey in this source aimed at detecting all C3H6O2 isomers with available spectroscopy. We […]
