BEETLE OF THE GODS

Jupiter clue

 

The first atomic bomb detonation, at the Trinity site in New Mexico in 1945, created a thin layer of glass on the sand. But the area of glass in the Egyptian desert is vastly bigger.

Whatever happened in Egypt must have been much more powerful than an atomic bomb.



 
Boslough's specialism is
modelling large impacts





Impact simulation 



A natural airburst of that magnitude was unheard of until, in 1994, scientists watched as comet Shoemaker-Levy collided with Jupiter. It exploded in the Jovian atmosphere, and the Hubble telescope recorded the largest incandescent fireball ever witnessed rising over Jupiter's horizon.

Mark Boslough, who specialises in modelling large impacts on supercomputers, created a simulation of a similar impact on Earth.

The simulation revealed that an impactor could indeed generate a blistering atmospheric fireball, creating surface temperatures of 1,800C, and leaving behind a field of glass.

"What I want to emphasise is that it is hugely bigger in energy than the atomic tests," said Boslough. "Ten thousand times more powerful."
