Ultra-fine stripes are revealed in the sharpest-ever image of the sun. These striations are known as photospheric striations, caused by dynamics in the sun's magnetic field.

The study revealed ultra-fine striations—alternating bright and dark lines—on the Sun’s surface, which are linked to subtle but significant variations in the Sun’s magnetic field.

The Daniel K. Inouye Solar Telescope captured the sharpest-ever images of the sun’s surface, revealing ultra-fine bright and dark stripes called striations that are caused by powerful magnetic ...
