NASA's solar probe discovered a groundbreaking structure in space

NASA’s Parker Solar Probe has detected a previously unrecognized, ordered structure within turbulent plasma flowing from the Sun, a finding researchers say could improve understanding of space weather and geomagnetic storms on Earth. The discovery emerged from analysis of complex plasma motions in the solar wind, where the hidden regularity had gone unnoticed until now. The result matters because better characterization of solar-wind turbulence can sharpen models of how charged particles and magnetic disturbances propagate toward Earth. Scientists will next work to determine how common the structure is and whether it can be incorporated into space-weather forecasting.
