Scientists using the Inouye Solar Telescope have captured new detail of the Sun’s surface, revealing magnetic vortices that influence space weather. The telescope, located on a high peak in Hawaii where clear blue skies are typical, provides high‑resolution images of the photosphere. The images reveal swirling patterns caused by the twisting of the Sun’s magnetic field by hot gas motions, identified as Kelvin‑Helmholtz instability. This instability creates magnetic energy that can accumulate and release as solar flares or coronal mass ejections, which travel into space and may disrupt Earth’s power grids, satellites, and pose risks to astronauts. Dr David Boboltz of the US National Solar Observatory said the new data enhance understanding of the physics that drive space weather and support prediction efforts. Dr David Kuridze, also of the NSO, said the twisting motions generate magnetic energy that fuels large‑scale solar explosions. Dr Friedrich Woeger noted that the findings clarify why the solar surface is hot and show how energy is transported upward before being released. The results were published in Nature and were made possible by the telescope’s high‑altitude site with minimal atmospheric interference. Continued study of these magnetic structures may improve space‑weather forecasts and deepen knowledge of solar physics.
