Friday August 19th 2022 Mark Boslough will be our guest of honour speaking about the 100 megaton airburst that occurred in ancient Egypt.
In February 2006, Mark participated in an expedition to Egypt to visit the site of an enigmatic natural desert glass with a film crew for the BBC documentary “Tutankhamun’s Fireball.” A piece of the glass had recently been identified in a scarab that adorned a breastplate found in King Tut’s tomb. There was little doubt that the glass was the product of an impact event, but the precise mechanism for its formation was a matter of debate. Simulations inspired by the expedition support the hypothesis that the glass was formed by heating and ablation of sandstone and sand near ground zero from a 100 megaton or larger airburst resulting from the breakup of an asteroid. The explosion was similar to the Chelyabinsk and Tunguska airbursts, but so big that the white-hot asteroid vapor cloud formed a fireball that descended all the way to the ground.
