It appears that scientists have finally solved the mystery of the Dakhla glass discovered in the Dakhla Oasis in 1987. The natural glass found in the Egyptian desert turned out to be products of a meteorite that crashed into Earth some 100,000 and 200,000 years ago.

According to Maxine Kleindienst, discoverer of the glass, "this meteorite event would have been catastrophic for all living things. Even a relatively small impact would have exterminated all life for [several] miles." The initial hypothesis was that the Stone Age glass could have been produced by burning vegetation or lightning strikes.

A chemical analysis, however, revealed a really high amount of temperature that there could be no other explanation for it except for a meteorite impact.

The detailed findings was published online in ScienceDirect.
