The giant crater was discovered in northern Siberia earlier this week in the Russian peninsula, Yamal, which translates to "the end of the world".
Last Friday, a helicopter crew filmed the incredible phenomenon that resembles the aftermath of a nuclear explosion or a giant wormhole from the movies.
It stands around 50 to 80 metres wide with nobody knowing how deep it is.
Web users have suggested all sorts of scenarios of how it came about from meteors to missile testing.
Some have even blamed it on aliens.
But despite still being unsure about its origins, experts have shunned the idea it was caused by a meteor.
Russia's Emergencies Ministry confirmed it was not caused by something out of space, saying a meteor that big would not have gone unnoticed.

A spokesman for the ministry's Yamal branch told the Siberian Times: "We can definitely say that it is not a meteorite."
A team of researchers now intend to visit the area to take samples of soil, air and water to assess what the real reason is.
Some experts have brought up the theory that it was a large underground explosion.
The area of Yamal contains large amounts of oil and gas that Russia uses to sell to Europe.
Anna Kurchatova from the Sub-Arctic Scientific Research Centre, believed the crater was formed by a reaction to a mixture of gas, salt and water.
She suggested the effects of global warming may have caused an 'alarming' melt in underground ice, released gas and caused the large scale explosion – blowing the giant hole in the ground.
