This December in a remote part of the Russian Arctic, scientists stumbled upon another type of glowing light, this time in the snow.

In the first documented sighting of its kind, scientists, led by microbiologist Vera Emelianenko observed faint blue lights glowing in the powdery white snow while working in the Arctic off the coast of the White Sea.

After collecting a sample and studying it under a microscope, he concluded the culprits were Metridia longa, a species of copepod.

The copepods were likely caught in a strong current in the White Sea that washed them ashore into the snow.

The glowing phenomenon is caused by a natural process called bioluminescence.

Light is created when luciferin, which copepods carry, mixes with oxygen creating a chemical reaction.

Metridia longa have glands on their heads and body which secrete their incandescence.

Russia is home to a variety of unique and fascinating things, one of which appears to be blue-glow bioluminescent snow.

Vera Emelianenko, a Russian biologist, went on a trip to the White Sea coast, high in the Russian Arctic, last month and spotted something strange in the snow: a blue glow resembling Christmas lights.

Known as "the sea's bugs," these insects are normally found in the water at depths of up to 100 metres at night, but only a few feet during the day, when they can generate the eye-catching bioluminescence phenomenon on beaches.
