Efforts to unveil the structure of the local interstellar medium and its recent star-formation history have spanned the past 70 years (refs. ^(1-6)). Recent studies using precise data from space astrometry missions have revealed nearby, newly formed star clusters with connected origins^(7-12). Nonetheless, mapping young clusters across the entire sky back to their natal regions has been hindered by a lack of clusters with precise radial-velocity data. Here we show that 155 out of 272 …
