NASA’s Parker Solar Probe detected a distinct magnetic pattern that reverses direction at very small scales within space plasma, Science Daily reported on Monday based on findings published in The Astrophysical Journal Letters.
Space turbulence affects everything from Earth’s magnetosphere to the solar wind and accretion disks. Researchers from ten countries struggled to explain how energy distributes through these constant fluctuations until identifying this organized structure.
“We see a clear structure in the spectrum, even though the turbulence represents unstructured motions,” Dr. Masatomi Iizawa from Technische Universität Braunschweig told Science Daily.
Plasma moves like a fluid at larger scales, forming swirling vortices and electromagnetic waves. Researchers found that magnetic fields rotate counterclockwise when viewed outward from the Sun at larger scales.
At much smaller scales, the preferred rotation switches to clockwise. As the solar wind moves further away from the Sun, this flip intensifies and transitions toward extended wavelengths.
“The results are of great significance for both plasma physics and astrophysics,” said Dr. Yokoi from the University of Tokyo.
Understanding this magnetic reversal helps researchers study shock waves and clouds of magnetic material traveling through interplanetary space. These solar eruptions drive geomagnetic storms that impact Earth’s technological infrastructure.
International teams from the Technische Universität Braunschweig, the University of Tokyo, Tohoku University, Kyushu University, and Osaka University contributed to the study.
Plasma moves like a fluid at larger scales, creating complex fluctuations through swirling structures called vortices and electromagnetic waves. Researchers found that magnetic fields follow consistent rotation patterns despite appearing random.
An international research team identified the phenomenon using observations collected by NASA’s Parker Solar Probe. The findings were published in The Astrophysical Journal Letters.
Plasma turbulence influences shock waves and clouds of magnetic material that follow solar eruptions, which drive geomagnetic storms. Better data on these mechanisms helps scientists improve space weather predictions.
