"Equinox and the Iron Sun" is a fascinating image of the Sun on the autumnal equinox. The term equinox is referring to the fact that earth will experience an equal number of daylight hours as nighttime hours on that day. This image of the sun gives great insight on the massive amount of activity that is always occurring within the sun. The spirals seen on various parts are areas of the highest activity, as they spirals are plasma caught in magnetic fields. It is fascinating that our sun is constantly producing the many elements that make up our universe, and we can see it happening with this image. This image of the Sun focuses primarily on the emissions of Iron Atoms, which is what gives this false colored image such a unique look.
