'Door to hell' burning since 42 years

  • Scientists set this 230-foot wide crater on fire in 1971 in order to search for natural gas reserves in a desert located in Turkmenistan. 

    They expected the crater to take only a few hours to burn out but instead, it's been over 40 years and the flames are still strong. 

    The team of researchers thought it would be best to light the crater on fire since they were worried it might release a poisonous gas. 

    The hole has become a popular tourist attraction and is considered to be one of the most bizarre places in the world to see.

    Locals refer to it as being the "Door to Hell."
