Star Furnaces Don't Incinerate Life express
Radio telescopes detected emissions from the celestial object G358.93-0.03 MM1 — a hot cocoon inside which a massive star is igniting. Within that glow, lines of glycolamide appeared, a delicate carbon molecule.
The fragile structure didn't fall apart near the growing sun, where the heat should have erased everything down to atoms.
Half-century-old ideas of Fred Hoyle that dust between stars can nurture complex organics have gained new support. Comparison with the cold cloud G+0.693-0.027 showed: the ratio of glycolamide and its relatives — formamide and acetamide — in the hot zone is the same as in the icy one. The heat was expected to scramble all proportions, but the recipe held firm. Like a cookbook surviving a toss into a scorching oven.
This fact suggests a unified 'amide network' linking hydrogen clouds to protostellar clumps. Chemical memory survives: the birth of suns doesn't erase molecular recipes. Life's ingredients, imprinted in cosmic dust, journey through stellar furnaces and remain recognizable.

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 glycine, was recently detected in the molecular cloud G+0.693-0.027. However, establishing its presence in warm, high-density environments is crucial to evaluate the chemical continuity of amides. Here we report the tentative detection of glycolamide in a hot molecular core, G358.93-0.03 MM1, using ALMA 1 mm observations. Seven unblended or only mildly blended emission lines were identified, yielding an abundance of (1.7$$\pm$$0.2)$$\times 10^{-10}$$ relative to H$$_{2}$$. The comparable formamide/glycolamide and acetamide/glycolamide abundance ratios in both sources suggest a chemically connected amide network across different environments. These results demonstrate that amides can persist and chemically evolve during massive star formation, tracing the chemical continuity from interstellar to protostellar environments.
Glycolamide is an isomer of glycine: swap two atoms, and you have the amino acid that makes up our proteins. Nature seems to have mixed up just one bond, creating a molecular draft.
Fred Hoyle, mentioned above, in his novel 'The Black Cloud' described an intelligent interstellar cloud. Now, in real clouds, organics have been found that withstand stellar heat and retain their molecular signature.
