This amazing picture of the sun was taken by Alan Friedman. We’ll just delve into the beauty of the image, but if you’re interested how he captured the image, read on.

Alan used a filter that lets through only a very narrow wavelength of light emitted by hydrogen (called Hα for those of you keeping track at home), so this tracks the activity of gas on the solar surface. He also inverts the image of the solar disk (makes it a negative) to increase contrast. Somehow this adds a three-dimensional quality to the picture, and reveals an amazing amount of texture. I swear I had a rug in my bedroom growing up that was this texture (though somewhat cooler and less burny).
