This is the largest coronal hole to be observed in the sun’s atmosphere for over a year!


Snapped through three of NASA Solar Dynamics Observatory‘s (SDO) extreme ultraviolet filters, this coronal hole is caused by a low density region of hot plasma.

Through the SDO’s eyes, coronal holes appear dark as there is a very low density of the multimillion degree plasma generating the EUV radiation. And as this dramatic observation demonstrates, to the eyes of the SDO, the sun really does appear to have a hole.
