A giant hole is found on the Yamal Peninsula, Siberia, Russia.
The television crew accidentally saw it while flying in the area and immortalized it.
What caused it?
This is the 17th hole found in the area and is strongly suspected to be the largest.
According to scientists, the appearance of the holes may have been due to melted permafrost or frozen soil layers.
The melting of the permafrost together with the expansion of methane gas caused the ice-covered mound to collapse and form the sinkhole.
The wild theory calls it the result of a meteor collision, weapons testing, or the act of aliens.
Scientists have so far been unable to determine what the real cause is.
What is clear is that this giant hole phenomenon was first discovered in 2014.
Subsequently, several large holes were found with similar patterns and sizes.
Vasily Bogoyavlensky, a scientist from Russian Oil and Gas Research, once believed that the hole was created due to climate change and human activity.
This he said because the Yamal Peninsula is the largest natural gas field in Russia which is often mined.
Natural gas that comes from this place is the main source of heating in Europe during winter.
Compared to before, this new finding is considered to be more massive.
This phenomenon occurs so quickly and in remote places that it is quite difficult for scientists to study it.
Moreover, the giant hole turned into a lake which made his research even more difficult.
