NASA captures sun looking like a spooky jack-o'-lantern

On October 8, the Solar Dynamics Observatory spacecraft captured a spooky sight in distant the sky: the sun looking like a menacing jack-o'-lantern, just in time for Halloween. Take a look in the gallery above.

The images were made possible by capturing the sun at different wavelengths of light on the extreme ultraviolet spectrum, which is not visible to the naked eye. To create the "jack-o'-lantern" photo, two sets of wavelengths were blended together.

According to NASA, the active regions of the sun combined to form the creepy smile as intense magnetic fields hovering over the sun's corona (plasma atmosphere surrounding the sun) produced enormous amount of light and energy. At an extreme low level of exposure, the sun appears dark and illuminated from the inside.
