Analyzing data collected by two Spanish telescopes, an international team of researchers detected nitrile in the molecular cloud G+0.693-0.027 near the center of the Milky Way. These biomolecules, the components of RNA molecules, are abundant in the universe.
Characterized by the presence of a cyano group – aof carbon attached to an atom by a triple bond -, belongs to the nitrile family important for life. Combined with a And to one ( ), form these molecules Its molecular components . l’ – I’m ribonucleic – present in almost all living things and perform many functions, esp cells are prominent.
Bricks of life in interstellar space?
In a new study, an international team of researchers analyzedCollected electromagnetic by two Spanish, when they observed G+0.693-0.027, located near the center of the Milky Way. And their discovery is rather exciting. among all They identified certain nitriles, never discovered before. Not currently which form in this Molecular – Dense enough to allow interstellar nebulae to form molecular – but scientists believe it could become a star nursery in the future. Its structure, which seems similar to some of our objects (like ) as well as some of our other star-forming regions Makes its study relevant for understanding .
Is there plenty of matter in the universe?
However, this is not the first time that such molecules have been observedSince they were detected in the TMC-1 molecular cloud in 2019 . Thus, combined with observations made over the past few years, scientists believe that the nitrile family is one of the most abundant in the universe. They are found in molecular clouds Comets, or even in of its satellite . Such a conclusion may favor the “RNA world” hypothesis, according to which RNA is the precursor of all living molecules, including And . According to this hypothesis, the components of RNA arrived on Earth thanks to bases and comets, and will not necessarily form in situ: we now know that they can form in interstellar space, especially in molecular clouds.
But scientists are keen to remain rational. Although this discovery is exciting, the presence of life on Earth required various other elements, viznecessary for cell formation, thus pointing to the need to focus on how they can form from common precursors in interstellar space.
