A new study published in the National Science Review reveals that the Solar Orbiter spacecraft has captured high-speed magnetic vibrations in the sun's polar regions. These vibrations, observed using images from the Extreme Ultraviolet Imager (EUI), may help explain how the fast solar wind—a stream of charged particles ejected from the sun—is accelerated. The research was led by Dr. Yuhang Gao and Professor Hui Tian at Peking University and used data from September 2021. The EUI, which takes images every five seconds with a resolution of 420 km per pixel, offers more than double the precision and speed of earlier instruments like NASA's Solar Dynamics Observatory (SDO), which captured images every 12 seconds with a lower resolution. To analyze the magnetic waves, the researchers used the Northumbria University Wave Tracking (NUWT) program. This algorithm detected 2,318 wave events from EUI data, compared to just 560 from SDO data. The EUI was particularly effective at detecting shorter wavelength waves—38% of those with periods under 100 seconds—compared to only 9% with SDO. Additionally, the average speed of plasma threads detected by EUI was 15.4 km/s, significantly higher than the 9.9 km/s measured by SDO. These faster waves carry 2.6 times more energy than previously estimated, suggesting that more energy is present in the sun's magnetic activity than previously thought. The study suggests three possible sources for these magnetic ripples: interactions between magnetic loops and unrelated field lines, formation as part of spicules—plasma jets that rise from the sun's surface—or turbulent cascades from larger waves. These vibrations might explain why the sun's outer atmosphere, known as the corona, reaches temperatures of over 1,000,000°C, far hotter than its surface. The energy from these waves could be transferred to the solar wind through processes like resonant absorption and phase mixing, helping to accelerate the charged particles that travel through the solar system. Despite these findings, the energy detected from the waves is still about ten times lower than what other models suggest is needed to fully launch the solar wind. This discrepancy may be due to technological limitations in current instruments. Future missions, such as the Solar Polar-orbit Observatory (SPO), scheduled for launch in early 2029, may provide better insights into the sun's magnetic activity and help resolve this gap in understanding.
