. This image taken by the instrument IMaX shows the granulation in the Sun's photosphere. In the bright regions, hot plasma wells to the surface; in the dark regions, the cooled plasma sinks down again. In between tiny, bright spots can be seen. The individual granules have a size of several thousand miles. The bright points measure approximately 60 miles (100 kilometers) in diameter. MPS
