More than one star contributes to the irregular shape of NGC 6072 – Webb’s newest look at this planetary nebula in the near- and mid-infrared shows what may appear as a very messy scene resembling splattered paint. However, the unusual, asymmetrical scene hints at more complicated mechanisms underway, as the star central to the scene approaches the very final stages of its life and expels shells of material, losing up to 80 percent of its mass.

The satellite will scan the Earth twice every 12 days.
