NASA : Image of Sun style Van Gogh

Nicholeen Viall, a solar scientist at NASA's Goddard Space Flight Center creates images of the sun reminiscent of Van Gogh, but it's science, not art. The color of each pixel contains a wealth of information about the 12-hour history of cooling and heating at that spot on the sun. That history holds clues to what drives the temperature and movements of the sun's atmosphere, or corona.
