Many Precursors For RNA Have Been Detected In Our Galactic Center
The heart of the Milky Way appears to be a hotspot for molecules that combine to form RNA. A new survey of the thick molecular cloud that shrouds the galactic center has revealed the presence of various nitriles – organic molecules that are often toxic in isolation, but are also molecular building blocks essential for life. The increase in prebiotic molecules (molecules involved in the emergence of life) identified at the center of galaxies, particularly those associated with RNA, has implications for our understanding of how life emerged in the Universe – and how it happened on Earth. “Here we show that the chemistry occurring in the interstellar medium is able to efficiently form some of the nitriles, which are key molecular precursors of the ‘RNA World’ scenario,” explains astrobiologist Víctor Rivilla of the Spanish National Research Council and National Institutes. Aerospace Technology in Spain. Exactly how life arose on Earth is a mystery that basic scientists are eager to achie
