State cheese!
On October 26, NASAs Solar Dynamics Observatory (SDO) caught the Sun “smiling.” Seen in ultraviolet light, these dark patches on the Sun are referred to as coronal holes and are regions where fast solar wind gushes out into area.

SDO has studied how the Sun creates solar activity and drives space weather condition since its launch in 2010. Its observations begin in the interior of the Sun with the solar dynamo– the churning of the Suns interior that develops its electromagnetic field and drives area weather. Even more out, SDO observes the solar surface to directly determine the solar atmosphere and the magnetic field. Lastly, SDO measures the severe ultraviolet irradiance of the Sun which is an essential chauffeur of the structure and structure of the Earths upper atmosphere.
