NASA’s Parker Solar Probe has uncovered hidden order in space turbulence, a finding that could help scientists understand magnetic storms on Earth.

Smoke rising from an incense stick can begin as a thin, steady stream before curling and spreading unpredictably. The smoke makes turbulence in the air visible. Turbulence also occurs in space, where the moving material is plasma, an ionized gas containing electrically charged particles. Electric and magnetic fields strongly influence how those particles move, making this turbulence different from the movements of ordinary air.

Space plasma is also so dilute that its particles rarely collide, making it effectively collisionless. Physicists are still working to understand how turbulence develops under these conditions and how its energy is distributed. Measurements from NASA’s Parker Solar Probe have now revealed an organized pattern within that irregular activity.
