NASA snaps Jack-o'-lantern on the face of the sun
CBS NEWS - The sun seems to be celebrating Halloween a few weeks early by putting on an unusually spooky "face." On Oct. 8, NASA captured the above photo of active regions on the sun that gave it the appearance of a jack-o'-lantern.
NASA explains the phenomenon on its website:
"The active regions appear brighter because those are areas that emit more light and energy -- markers of an intense and complex set of magnetic fields hovering in the sun's atmosphere, the corona. This image blends together two sets of wavelengths at 171 and 193 Angstroms, typically colorized in gold and yellow, to create a particularly Halloween-like appearance."
NASA also posted a photo of the sun in extreme ultraviolet light:
