The sunspots in the images are dark and cooler regions on the sun’s surface, known as the photosphere, where strong magnetic fields are found, according to the National Solar Observatory.

The 4,096 by 4,096 sensor gives the AIA a resolution of 0.6 arcseconds per pixel, and the optics allow imaging out to almost 1.3 solar radii, to capture fine detail in the thin solar atmosphere.

Magnetic snake-like energy patterns could help explain a lingering solar mystery: why the sun's outer atmosphere of the sun is so much hotter than its lower layers.
