Still, space scientists knew that the icy dust bodies that formed carbonaceous chondrites were likely to contain water, ammonia and small carbon molecules like aldehydes and methanol, so the elemental constituents of amino acids would have been present. They needed only a source of energy to facilitate the reaction. Experimental work suggested that ultraviolet radiation from supernovas could have been strong enough to do it. Collisions between the dust bodies could also have heated them enough to produce a similar effect.
Me llama la atención como se da a entender que no solo basta con tener los "ingredientes" necesarios para la vida, también se necesita una fuente de energía para que la vida florezca, dando a entender que todo fue un proceso que necesitó un impulso en su inicio
