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.
