    Stars are formed hidden behind layers of dust and cold gas. The younger the stars are the more difficult it is to observe them through the veils of dust. In regions too heavily obscured to be accessible at optical wavelengths, long-wavelength observations of carbon (C), nitrogen (N) and oxygen (O)-bearing molecules become very important. They may be the only way to trace the earlier stages of star formation. Their C, N and O isotopologues are of particular interest since each of the isotopologues is formed under specific physical conditions and uniquely track the stellar growth in the Universe. The isotopologue ratios are believed to trace gas infall, enrichment by stars and gas physical conditions. Thus, the analysis of carbon and oxygen isotopologue ratios is not only relevant for the formation of our Solar System and the Milky Way, but is also important to understand nearby and starburst galaxies, as well as luminous distant galaxies.

    With this conference we will bring together researchers from the Galactic and extragalactic communities studying the relevance of C, N and O isotopologue ratios for stellar processes and for how stars evolve. So far each community has been working separately. Now it is time to bring all these researchers together to work on a picture that considers the small and large scales, from the Milky Way to the Early Universe.
