Star Furnaces Don't Incinerate Life ⚡ экспресс
To test the chemical continuity of amides, a search for glycolamide was conducted in the hot molecular core G358.93-0.03 MM1. Using ALMA data at 1 mm wavelength, seven unblended or slightly blended emission lines corresponding to this molecule were identified. The abundance of glycolamide is estimated at (1.7±0.2)×10⁻¹⁰ relative to H₂. The formamide/glycolamide and acetamide/glycolamide ratios in this source are close to those previously obtained for the G+0.693-0.027 cloud. This points to a unified amide chemical network that persists during the transition from the interstellar medium to protostellar objects. Thus, amides can endure the harsh conditions of star formation, ensuring chemical continuity in the evolution of molecular matter.
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.
🎯 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.
