Millions of rare bioluminescent plankton formed into a bunch of blue beams and lit up the tranquil ocean in Penmon, Wales. /VCG Photo  

An amateur photographer Paul Joinson captured the astonishing moment when the plankton gathered along the sea coast of the Irish ocean and created a stunning blue light. /VCG Photo

The magical glow was created by a kind of chemical called luciferin. The organisms produce the chemical on their own and the light emitted by the plankton is called “cold light,” since less than 20 percent of the light generates heat. /VCG Photo
