Alan Friedman caused a sensation for a series of pictures, exacted with creative camera manipulation, of that little ball in the sky that, more or less, is responsible for all life on Earth.  When the images were published in Discover magazine and then at the Huffington Post, he wowed the world. 

Friedman, an art photographer and amateur astronomer (amateur only in the sense that he doesn't work for a government or academic agency),  used a special filter to show Hα (H-alpha) light waves, also known as the pure fumes of hydrogen that form the burning nova as the center of our orbit.

Explained Discover about Friedman's method which produced the picture, below:

"The Sun's surface puts out light at all wavelengths, but the surface isn't solid. It's a gas, and it tapers off with height. Normally, a thin gas in space emits light at very specific colors as electrons jump from one energy level to another in the individual atoms. But compressed gas in the thicker, denser part of the Sun mashes together all those energies, spreading them out, so it emits white light (that layer of the Sun is called the photosphere). Above that layer, where the gas is thinner (in a layer called the chromosphere), the hydrogen does emit light at specific colors. One of these, Hα, is in the red part of the spectrum, and in fact hot, thin hydrogen emits very strongly in Hα.
