3D approximation of the region surrounding the Perseus and Taurus molecular clouds. The approximate locations of the Perseus and Taurus molecular clouds are shown as red circles, and the Per-Tau shell (Bialy et al. 2021) is shown as a gray sphere. The Sun is depicted as a yellow circle and the line-of-sight path connecting the Sun to the center of the Per-Tau shell is shown as a dashed line. The Per2 shell-like structure is approximated as a sphere located behind the Perseus cloud, shown in green. The size of the Taurus and Perseus clouds and the Sun are not depicted to scale.
