English: SN 2021aefx in NGC 1566 at ≈2–21 μm. Left panel: MIRI F1130W PHANGS-JWST image of NGC 1566 showing the location of SN 2021aefx, marked with a green circle. Right panels: zoom-ins on SN 2021aefx in each PHANGS-JWST filter. The top four panels show 200 pc × 200 pc cutouts from NIRCam images at 2.0–3.6 μm. The bottom four panels show 1 kpc × 1 kpc MIRI images at 7.7–21 μm. The inner green circle marks the aperture used in the photometry measurement, and the two concentric dashed cyan circles mark the inner and outer apertures used for the background subtraction.
