VISIR image of the Homunculus nebula at 12.5 μm in 2018, tracing the thermal emission from heated dust and the H I 7−6 emission. The field of view is 25″ × 25″, and the spatial resolution is 0.3″. The flux density in Jy per detector pixel (0.045″ pixel⁻¹) is shown as well as the integrated flux along the image axes. The brightest knot in the center of the nebula is due to a shell that surrounds the star, to an inner torus or disk, or to a pin-wheel structure, and it includes the Weigelt complex (Weigelt & Ebersberger 1986). The two bright loops form the Butterfly nebula from which 50% of the integrated flux originates.
