The Milky Way’s neutral hydrogen (H i) disk is warped and flared1,2. However, a dearth of accurate H i-based distances has thus far prevented the development of an accurate Galactic Disk model. Moreover, the extent to which our Galaxy’s stellar and gas disk morphologies are mutually consistent is also unclear. Classical Cepheids, primary distance indicators with distance accuracies of 3–5% (ref. 3), offer a unique opportunity to develop an intuitive and accurate three-dimensional picture.
