A poll led by the Pew Global Attitudes Project has canvassed more than 48,000 people from all different cultures, religions and nationalities to discover what they believe to be the greatest current threats facing humanity in the 21st century.

People from 44 different countries were given a list of potential threats and asked to name which of these constituted their greatest fears for the human race, answering the question:

"Which one of these poses the greatest threat to the world?"

There is a place in Siberia known as Yamal, which literally translates as "the end of the world."

It is an area that is notorious for earth-shattering events, as this was the region where the most dangerous meteor in recent history struck in 1908 with devastating results. Thankfully, the blast occurred in a relatively uninhabited zone, but forests were levelled over a distance of 2000 square kilometers (1242 miles).

Yamal is now the site of another unlikely happening in the form of a huge, unexplained crater, estimated by observers to be around 50 meters (164 feet) wide and 70 meters (229 feet) deep with water from melting permafrost cascading down its sides into snow-covered depths.

Unknown Country has been keeping a keen eye on the skies just recently, and with good cause: following the revelation last week that the Earth had narrowly escaped serious damage from 26 very sizeable asteroids over the past few years, another lucky escape was reported over the weekend.

Astronomers are warning us that asteroid 2014 DX110 is on target to hurtle between the Earth and the Moon on Wednesday, passing close to our planet at a distance of just 217,000 miles (350,000km).

At 98ft (30m), 2014 DX110 is a relatively large object belonging to the Apollo class asteroid group, a class of Earth-crossing objects that pose a potential threat of impact. Scientists are currently aware of 240 Apollo asteroids, but it is thought that there could be at least 2000 Earth-crossers with diameters of 1 km or larger. If one of these giants hit Earth, it could carve out a crater about 10-20 times its own size.
