[EMAIL PROTECTED] Interstellar Space Molecules That Help Form Basic Life Structures Identified

The detection of this molecule suggests that a large number of the key components in prebiotic terrestrial chemistry could have been present in the interstellar matter from which the Solar System was formed. * IAC researchers Susana Iglesias Groth, Arturo Manchado and Aníbal García, in collaboration with Jonay González (Paris Observatory) and David Lambert (University of Texas) have just published these results in Astrophysical Journal Letters. The naphthalene was discovered in a star formation region in the constellation Perseus, in the direction of the star Cernis 52. “We have detected the presence of the naphthalene cation in a cloud of interstellar matter located 700 lightyears from the Earth”, says IAC researcher Susana Iglesias Groth. The spectral bands found in this consstellation coincide with laboratory measurements of the naphthalene cation. Iglesias Groth further adds, “we aim to investigate whether other, more complex, hydrocarbons exist in the same region, including aminoacids”. When subjected to ultraviolet radiation and combined with water and ammonium, both very abundant in the interstellar medium, naphthalene reacts and is capable of producing a wide variety of aminoacids and naphthaloquinones, precursor molecules to vitamins. All these molecules play a fundamental role in the development of life as we know it on Earth. In fact, naphthalene has been found in meteorites that continue to fall to the surface of the Earth, and which fell with much greater intensity in epochs preceding the appearance of life."
