Clay tablet holds clue to asteroid mystery

Now researchers say their translation of symbols on a star map from an ancient civilisation includes notes on a mile-wide asteroid that later hit Earth - which could have caused tens of thousands of deaths.
The circular clay tablet was discovered 150 years ago by Sir Austen Henry Layard, a leading Victorian archaeologist, in the remains of the royal palace at Nineveh, capital of ancient Assyria, in what is now Iraq.
The tablet, on display at the British Museum, shows drawings of constellations and pictogram-based text known as cuneiform - used by the Sumerians, the earliest known civilisation in the world.
A historian from Azerbaijan, who believes humans originally came to Earth from another planet, has interpreted it as a description of the arrival of a spaceship. More mainstream academics have failed to decipher its meaning.
Now Alan Bond, the managing director of a space propulsion company, Reaction Engines, and Mark Hempsell, a senior lecturer in astronautics at Bristol University, have cracked the cuneiform code and used a computer programme that can reconstruct the night sky thousands of years ago to provide a new explanation.
They believe their calculations prove the tablet - a copy made by an Assyrian scribe around 700 BC - is a Sumerian astronomer's notebook recording events in the sky on June 29, 3123 BC.
The pair say its symbols include a note of the trajectory of a large object travelling across the constellation of Pisces which, to within one degree, is consistent with an impact at Köfels.
Mr Hempsell said: "All previous work has drawn a blank on what the tablet is about.
 Köfels, in the Austrian Alps, where an asteroid is thought to have hit 5,000 years ago |
The Köfels site was originally interpreted as an asteroid impact, however the lack of an obvious impact crater led modern geologists to believe it to be simply a giant landslide.
However, the Bond-Hempsell theory, outlined in their book published today, A Sumerian Observation of the Köfels Impact Event, suggests that the asteroid left no crater because it clipped a mountain and turned into a fireball.
Mr Hempsell said: "The ground heating, though very short, would be enough to ignite any flammable material, including human hair and clothes.
"It is probable more people died under the plume than in the Alps due to the impact blast."
He added that extreme changes caused to rock and other substances at the site had previously led to the Köfels impact being erroneously dated to around 8,000 years ago.
