Orion’s Veil Protrusion

Infrared image of Orion Nebula with curved and dashed lines over it showing outflows, rims, lobes, shells, and protrusion along with location of Trapezium stars.

Schematic picture of the protrusion (green lines, center right) and outflows of ionized carbon extending beyond the protrusion – where the shell has likely been pierced – overlaid on a Wide-field Infrared Survey Explorer image of the region. Credit: NASA/JPL-Caltech/WISE Team; Kavak et al.
