A portrait of the sun in the wavelength of hydrogen alpha light. A fine art print of this image is available for sale. © Alan Friedman
This image of the sun taken by Buffalo, N.Y., photographer Alan Friedman has become an Internet sensation, thanks to the massive image's eye-popping amount of detail.
Friedman attached a hydrogen-alpha filter to his telescope to improve the visibility of the sun's surface detail. After all, the sun burns through 600 million tons of hydrogen a second.
The images were originally black and white. Friedman added some color, choosing orange to give the average earthling a sense of familiarity.
