After More Than 60 Years of Famous Christmas Carol, Scientists Finally Explain Rudolph’s Red Nose

On Wednesday, scientists finally came up with an explanation why Rudolph's nose is red. Rudolph belongs to the Rangifer tarandus species.

Remember, after all, that during Christmas, Rudolph has a lot of sleigh-pulling to do beginning from the North Pole where his master resides.
