Here's a photo of the sun that NASA recently released. I thought it resembled a jack-o-lantern as designed by expressionist artists and lit with a dozen road flares inside the pumpkin.
At this site you can see what jack-ol-lanterns lit with road flares do look like.
I love to play jack-o-lantern on Hallowe'en-- I sit in a window and get lit!
You can carve a virtual jack-o-lantern here.
