The Visible Light Sun

This is a picture of the Sun's visible layer; the layer you see from the Earth's surface. This layer of the Sun is the furthest we can see by direct means. It is called the photosphere.

This image has recorded all wavelengths of visible light emitted from the Sun. No single wavelength has been filtered out, but a filter was used to reduce the amount of light. The Sun is very bright. When we look at the Sun we must reduce the brightness so we do not damage our eyes or our camera. This image was taken by a telescope at the Catania Astrophysical Observatory in Italy.
