The cosmic “paintbrush” that creates some of the most dazzling images in the night sky may have been found by researchers at the University of Rochester, a paper in the January 25 issue of Nature suggests. A magnetic dynamo similar to the kind that produces storms on our sun appears to shape planetary nebulae, the wispy clouds of light that radiate from some dying stars. The scientists have shown that as some stars die and expel their outer layers, they generate massive magnetic fields that twist the radiating material into beautiful and distinctive shapes.
