Experts examine the newly-discovered hole in the earth in Siberia.

The crater on the Yamal Peninsula was caused by aliens, a meteorite, a stray missile, or an explosive gas cocktail released due to global warming, according to various theories in recent days.
Images of the remarkable phenomenon have gone round the world since The Siberian Times highlighted helicopter images of the giant hole earlier this week.
The first expedition to the scene – the scientists have just returned – took these epic pictures of the hole, including the darkening pattern on the inner rim.
Now they are using Russian satellite pictures to fix the moment when it suddenly formed.
They found the crater – around up to 70 metres deep – has an icy lake at its bottom, and water is cascading down its eroding permafrost walls.
It is not as wide as aerial estimates which suggested between 50 and 100 metres.
