This photograph was taken by the crew on board the Columbia during its last mission, on a cloudless day. The picture is of Europe and Africa when the sun is setting. Half of the picture is in night. The bright dots you see are the cities’ lights. Note that the lights are already on in Holland, Paris, and Barcelona and that’s it’s still daylight in Dublin, London, Lisbon and Madrid
The Darvaza Gas Crater in Turkmenistan also known as “The Door to Hell” was discovered when a rig drilling for gas hit the gas-filled cavern. The hole was soon lit on fire to avoid releasing methane into the air and has been burning for 40 years.
