Interstellar ices were simulated by condensing and UV irradiating molecules such as H 2 O, CH 3 OH, and NH 3 at 80 K. Multidimensional gas chromatography analyses allowed for the identification of 26 amino and diamino acids (see graph). The results support the suggestion that potentially prebiotic molecules originating from the photochemistry of interstellar ices could have been incorporated in cometary dust and delivered to the early Earth.
