While everyone has seen what looks like a man’s face on the surface of the Moon, nobody has ever seen any on the surface of the Sun… Nobody except SDO.
In the video below, a set of pictures taken by the Solar Dynamics Observatory Spacecraft shows the Sun in different wavelengths. The pictures, taken on December 9, 2010, are shown in order from the lowest temperature material being imaged to the highest. As the images go further from our star’s surface, out to its upper corona, the features of a face begin to appear.
Finally, this “old man in the Sun” is a good way to remember that in different wavelengths, the same object reveals different features.
