According to Wikipedia, a 'goblin' is a small, monstrous creature almost always grotesque, mischievous, and outright malicious, often having 'magical abilities' similar to a demon which are found in the folklore and mythologies of countries all across the world through time. Cast by author J.R.R. Tolkien in The Hobbit and The Lord Of The Rings as 'the great evil race of Middle-Earth', goblins have served as a main antagonist in stories and myths going back hundreds of years, aggressive and belligerent little creatures. 

Yet the 'Goblin' going viral seen in story after story in news all over the internet today has nothing to do with Tolkien nor the hideous, aggressive little monsters found in myth's through time but the latest outer space discovery that astronomers now say are helping to redefine the solar system that we live within.
