These images show the Sun right now as seen from the SDO. The one in the upper left is from the 4500Å filter. It shows the photosphere, what we think of as the light-emitting surface of the Sun. There are some very obvious sun spots just to the west of center. The other three images are composites, each made from a combination of three original data sets taken from various filters on the Solar Dynamics Observatory satellite.
