Evidence Of Comet Strike, A team of South African scientists writing in the journal ‘Earth and Planetary Science Letters’ said that they have found the first evidence of a comet striking Earth 28 million years ago.
“Comets always visit our skies – they’re these dirty snowballs of ice mixed with dust – but never before in history has material from a comet ever been found on Earth,” said David Block, a member of the research team and a professor of the University of the Witwatersrand.
The researchers said that the comet shot into Earth’s atmosphere and blew up above what is now known as Egypt with blast that wiped out every living thing in its path.
As the fireball exploded it created a super-hot shock wave that heated the sand on the surface to about 2,000 degrees Celsius. The extreme heat and pressure formed a great quantity of yellow silica glass that was spread throughout a 6,000 square kilometer area of the Sahara that’s known as the Libyan Desert Glass strewn field.
