As Halloween approaches, even the Sun can’t contain its excitement. While last week’s lunar eclipse woke many up early, NASA snapped a shot of the Sun. A slight change to the image and boom, a Jack O’Lantern.

Two wavelengths were blended together in the image above to get the Sun prepped for Halloween. Specifically, wavelengths at 171 and 193 Angstroms.

The bright orange spots peppering the Sun? Those represent intense magnetic fields hovering just above the sun in the corona. 171 Angstroms show’s the sun’s atmosphere, while 193 Angstroms shows the bright, hotter regions of the corona.

NASA released a set of images showing off the sun in varying wavelengths. Check them out below.
