Journal ArticleDOI
Amino acids from ultraviolet irradiation of interstellar ice analogues.
G. M. Muñoz Caro,Uwe J. Meierhenrich,W. A. Schutte,Bernard Barbier,A. Arcones Segovia,H. Rosenbauer,Wolfram Thiemann,A. Brack,J.M. Greenberg +8 more
TL;DR: The results demonstrate that the spontaneous generation of amino acids in the interstellar medium is possible, supporting the suggestion that prebiotic molecules could have been delivered to the early Earth by cometary dust, meteorites or interplanetary dust particles.
