Left: observed magnetic field in the Pillars of Creation from Pattle et al. (2018). Right: projection zoomed in on two pillars forming in High_B at 3.34 Myr of 1 pc × 1 pc with the direction of the magnetic field overplotted. The visual comparison identifies three zones: the head, where the magnetic field remains anchored to the gas; the body, where it is dragged and aligns with the filament or pillars; and the base, where the expansion compresses B onto the shell of the H II region.
