New research utilizing data from NASA's Parker Solar Probe has provided the first direct evidence of a phenomenon known as the "helicity barrier" in the solar wind. This discovery, published in Physical Review X by Queen Mary University of London researchers, offers a significant step toward understanding two long-standing mysteries: how the sun's atmosphere is heated to millions of degrees and how the supersonic solar wind is generated.
