Big Bear Solar Observatory white light image

The Sun emits electromagnetic radiation at many wavelengths across the EM spectrum. These images show the Sun in the infrared, visible light, four different ultraviolet wavelengths, and in X-rays. Images taken in very narrow bands have the wavelengths of the associated waves noted (in nanometers). The photosphere is most prominent in the visible light images, while UV and X-ray views show details of the solar atmosphere. Note that almost all of these images are "false color" representations, since your eyes cannot see X-rays or ultraviolet or infrared "light".

Here are some current or recent views of the "surface" and atmosphere of the Sun:

• The Sun's Surface Now
• The Sun's Upper Atmosphere Now
• The Sun's Expanding Outer Layer (the Corona)
