NASA released an image of the sun this weekend looking more like a pumpkin than a star. The image, produced by NASA’s Scientific Visualization Studio, combines pictures of the sun in two different wavelengths of light (171 and 193 angstroms) that are typically colored gold and yellow. The resulting composite photo creates something that looks like the face of a Jack-O-Lantern.
The process is explained here.
The brighter spots in the image are the “active regions,” which “emit more light and energy,” according to NASA. They’re “markers of an intense and complex set of magnetic fields hovering in the sun’s atmosphere, the corona.”
That’s one really creepy sun.
