This fascinating article describes the effects of a Tunguska-sized airburst over the ancient city of Tall el-Hammam. It was originally published in The Conversation... A giant space rock demolished an ancient Middle Eastern city and everyone in it – possibly inspiring the Biblical story of Sodom Artist’s evidence-based depiction of the blast, which had the power of 1,000 Hiroshimas. Allen West and Jennifer Rice , CC BY-ND Christopher R.

Flashing through the atmosphere, the rock exploded in a massive fireball about 2.5 miles (4 kilometers) above the ground. The blast was around 1,000 times more powerful than the Hiroshima atomic bomb. The shocked city dwellers wh

New findings based on studying skeletal remains clearly indicates the Anglo-Saxons were a melting pot of people from both migrant and local cultural groups and not one homogenous group from Western Europe. Professor Keith Dobney at the University of Sydney said the team's results indicate that "the Anglo-Saxon kingdoms of early Medieval Britain were strikingly similar to contemporary Britain - full of people of different ancestries sharing a common language and culture". The Anglo-Saxon (or early medieval) period in England runs from the 5th-11th centuries AD. Early Anglo-Saxon dates from around 410-660 AD - with migration occurring throughout all but the final 100 years (ie 410-560AD).
