In an earlier post, I had mentioned the annual appearance of fireflies. There are other light-emitting creatures that exist in particular domains.
Bioluminescence-a number of creatures are found throughout marine habitats, from the ocean surface to the deep seafloor. One lovely folktale describes the above photo as a tapestry woven by mermaids. Doug Perrine
Aurora borealis-Energized particles from the sun slam into the ionosphere where Earth's magnetic field deflects these particles towards the Poles. These dancing lights to many ancient cultures represented spirits of the air. Arctic-Images

Sprites-Red Sprites can appear directly above an active thunderstorm 31-56 miles above the cloud top as a large
but weak flash. They usually happen at the same time as powerful
positive cloud to ground lightning strokes. Sprites are mostly red and usually last no more than a few
seconds, and their shapes are described as resembling jellyfish,
carrots, or columns. Because sprites are not very bright, they can only
be seen at night. They are rarely seen with the human eye, so they are
most often imaged with highly sensitive cameras. Stephane Vetter
