Charting a map of the densest gas clouds in the Milky Way will lead us to the hidden corners of our home galaxy where new stars form. It is not surprising as stars are basically extra-dense clouds of gas that shine with light produced by fusing hydrogen nuclei in their cores. Mapping the locations of the densest clouds is therefore equivalent to finding stars-to-be before their nuclear engines turn on. Creating detailed maps of gas and dust in the Universe is therefore crucial to outlining the environments in which stars and planets form (a vision that kept appearing in the recent 230th AAS meeting).We know quite little about the baby-hood of massive stars – the sites where baby massive stars are born are typically very far away, and they are usually blocked by dust. Moreover, massive stars typically form and evolve into clusters. In order to piece together a ...
