An ancient disaster

Researchers have found conclusive evidence that a massive cosmic airburst destroyed the biblical city of Tall el-Hammam in the Jordan Valley around 3600 years ago. The impact, which is believed to be equivalent to a 12-megaton explosion, was characterized by temperatures exceeding 2,000°C and the formation of melted metals and glass.
