In the image, we can see many interesting features of the Sun's surface, including:
Granules: These are small, bright cells that are caused by convection currents in the Sun's plasma. They are typically about the size of Texas.
Sunspots: These are dark, cool regions on the Sun's surface that are caused by strong magnetic fields. The dark cores of sunspots can be thousands of kilometers wide.
Prominences: These are bright, looping features that erupt from the Sun's surface. They are made of hot plasma that is trapped in the Sun's magnetic field.
