An enormous mysterious crater has left scientists scratching their heads after its discovery in northern Siberia.

Footage of the anomaly was filmed on Friday 11 July from a passing helicopter by engineer Konstantin Nikolaev as he and several others flew over the Russian peninsula called Yamal, which translates as "the end of the world".

The hole is roughly 30 kilometres from Yamal's biggest gas field Bovanenkovo. While the exact size of the crater is yet to be measured, the pilots believe it is wide enough to hold several Mi-8 helicopters inside.
