                          Dark Ball in Inverted Starfield

      Explanation: Does this strange dark ball look somehow familiar? If so,   
      that might be because it is our Sun. In the featured image from 2012, a   
      detailed solar view was captured originally in a very specific color of   
      red light, then rendered in black and white, and then color inverted.   
      Once complete, the resulting image was added to a starfield, then also   
      color inverted. Visible in the image of the Sun are long light   
      filaments, dark active regions, prominences peeking around the edge,   
      and a moving carpet of hot gas. The surface of our Sun can be a busy   
      place, in particular during Solar Maximum, the time when its surface   
      magnetic field is wound up the most. Besides an active Sun being so   
      picturesque, the plasma expelled can also become picturesque when it   
      impacts the Earth's magnetosphere and creates auroras.
