This imagery of the sun captured by NASA's Solar Dynamics Observatory from May 17-19, 2016, shows a giant dark area on the star's upper half, known as a coronal hole. 

Coronal holes are low-density regions of the sun’s atmosphere, known as the corona. Because they contain little solar material, they have lower temperatures and thus appear much darker than their surroundings. Coronal holes are visible in certain types of extreme ultraviolet light, which is typically invisible to our eyes, but is colorized here in purple for easy viewing.

NASA has revealed that a massive hole, measuring more than ten per cent of the Sun's surface area, has opened up on our star.
