Scientists using the Daniel K. Inouye Solar Telescope have captured the highest-resolution images of the Sun’s visible surface. The observations revealed tiny swirling magnetic structures that may explain how the Sun stores and releases energy, helping researchers better understand solar storms that can affect Earth.
The research was carried out by National Solar Observatory (NSO) scientists using the Daniel K. Inouye Solar Telescope in Hawaii. Dr. David Kuridze, assistant astronomer at the National Solar Observatory, led the study, which was published in the journal Nature. According to the National Solar Observatory and CNN’s reporting, the team combined telescope images with advanced computer simulations to confirm the discovery.
The study helps solve a long-standing mystery in solar physics. Scientists have known that the Sun’s magnetic field powers solar flares and coronal mass ejections, but they did not fully understand how this energy builds up. The newly observed swirling patterns provide a possible explanation for this process and may also help explain why the Sun’s outer atmosphere is much hotter than its surface.

The researchers found small whirlpools created by a process called Kelvin-Helmholtz instability. These swirls form where fast-moving plasma flows past slower-moving plasma. The tiny vortices twist the Sun’s magnetic field, transfer energy to smaller scales, and release heat. This process was observed on the Sun for the first time using the telescope’s high-resolution imaging.
The discovery could improve space weather forecasting. Better understanding of the Sun’s magnetic activity may help scientists predict powerful solar flares and coronal mass ejections that can disrupt satellites, GPS systems, radio communications, and power grids on Earth. The findings could also improve future solar research.
The research is still ongoing. Scientists need more observations to fully understand how these small whirlpools lead to larger solar events. Future studies will also examine how the newly discovered process can improve predictions of solar storms.

The findings show how advanced telescopes are changing our understanding of the Sun. According to the National Solar Observatory, the Daniel K. Inouye Solar Telescope is giving researchers an unprecedented view of the Sun’s smallest features. This could lead to more accurate space weather forecasts and a better understanding of how our closest star works.
