Observed magnetic fields in the vicinity of the Perseus molecular cloud. The B_⊥ lines were observed by the Planck Space Observatory and the B_‖ were obtained by Tahani et al. (2018). The red and drapery lines show the B_⊥, and the blue (red) circles show magnetic fields toward (away from) us. The size of the circles represents the strength of the magnetic fields. The background color image is the visual extinction map obtained by Kainulainen et al. (2009).
