With the power of the world’s largest solar telescope, astronomers have successfully glimpsed the sun’s roiling surface in never-before-seen detail. Inouye Main Full ViewThe sun’s visible surface—known as the photosphere—is only a thin portion of its overall atmosphere, but it’s where fluid plasma emits all of the star’s visible light. To successfully examine these complex structures, astronomers used data collected by the National Science Foundation’s Daniel K. Inouye Solar Telescope in Hawaii. Overview of Inouye Images and SimulationsAnalysis of the granule fringes’ wavelike behavior revealed further evidence of Kelvin-Helmholtz instabilities across the sun’s surface. The interactions can be seen everywhere from lake surfaces to planetary atmospheres—but it’s now clearer than ever that they occur on the sun’s surface, too.
