Scientists Directly Observe ‘Torsional Waves’ in sun’s atmosphere for First Time
New observations from the Daniel K. Inouye Solar Telescope in Hawaii have, for the first time, directly detected torsional magnetic waves within the Sun’s atmosphere, a phenomenon long theorized to be crucial to understanding the star’s energy generation and impact on Earth.The breakthrough, reported May 21, 2023, allows scientists to visualize the “invisible dance” of plasma and magnetic fields that drives solar activity.
The research, led by Professor richard Morton of Northumbria University (United Kingdom), utilized an innovative analytical method to isolate the twisting movements within the telescope’s data. “Plasma motion in the solar corona is dominated by rolling oscillations that mask twisting,” Morton explained.”We developed a way to eliminate that sway so we could see the pure torsion.We were finaly able to directly observe these movements, which have been hidden from our view for decades.”
The Daniel K. Inouye Solar Telescope is operated by the united States National Science Foundation (NSF). The Northumbria team also contributed to building the telescope’s broadband visible imaging system as part of a British solar instrumentation consortium.
Understanding these waves is expected to considerably improve space weather prediction, as variations in solar energy directly affect satellites, electrical networks, and terrestrial communication systems. “This research provides crucial validation to theories about how Alfvén wave turbulence drives the solar atmosphere,” Morton added. “For the first time we can compare theoretical models with real observations.”
The discovery represents a major advancement in solar observation, potentially unlocking key insights into how the Sun generates energy, maintains its extreme temperature, and influences the space surrounding Earth.
