Super high-definition images of the sun's sunspots have been captured by a telescope, showing tiny dots of plasma bubbling away within the dark spot.

The images were taken by National Science Foundation's (NSF) Daniel K. Inouye Solar Telescope in Hawaii, which is the world's most powerful ground-based solar telescope. The pictures show the sunspots as dark splotches on the sun's orange surface, spotted with pin-prick flashes of orange known as "umbral dots."
