Scientists have produced the most detailed images ever captured of the Sun’s surface, uncovering a remarkably dynamic and unusual landscape.
Although viewing the Sun directly is unsafe without proper eye protection, researchers were able to examine its intensely hot surface using the National Science Foundation’s Daniel K. Inouye Solar Telescope on Maui, Hawaii.
The images were initially taken to calibrate and test the telescope’s performance. However, the team soon realized they had recorded the Sun’s bright outer layer with a level of clarity never achieved before.
Among the most striking discoveries were delicate, feather-like patterns spreading across the solar surface.
Solar physicist Ruizhu Chen of Stanford University, who was not involved in the study, said the swirling structures reminded her of the dramatic skies depicted in Vincent van Gogh’s Starry Night.
The researchers identified these patterns as ripples caused by magnetized plasma moving at varying speeds, creating instabilities similar to waves formed when wind blows across water. While this fluid-dynamics phenomenon has been observed on Earth and on planets such as Jupiter and Saturn, study co-author Friedrich Wöger of the National Solar Observatory noted that it has never before been seen so clearly on the Sun’s surface.
