Image of the supernova remnant G54.1+0.3 combining X-rays from Chandra (blue), infrared PAH emission (green) and small dust grains (red) from Spitzer. The X-rays from the center of the supernova remnant arise from a pulsar wind nebula. The infrared emission from the supernova remnant arises from swept-up interstellarmaterial and freshly-formed dust. Some of the stars are engulfed by supernova dust; those stars are surrounded by a yellow glow from the grains which are heated by the stars as they pass close by. The white graph shows the infrared spectral energy distribution of the shell, together with a model of emission from silicates and corundum (see Temim et al.; 2017 ApJ 836, 129).
