Tutankhamen’s Brooch Linked to Evidence of Comet Striking Earth

Via The University of Witwatersrand, Johannesburg:

The first ever evidence of a comet entering Earth’s atmosphere and exploding, raining down a shock wave of fire which obliterated every life form in its path, has been discovered by a team of South African scientists and international collaborators, and will be presented at a public lecture on Thursday.

The discovery has not only provided the first definitive proof of a comet striking Earth, millions of years ago, but it could also help us to unlock, in the future, the secrets of the formation of our solar system.

“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,” says Professor David Block of Wits University.

The comet entered Earth’s atmosphere above Egypt about 28 million years ago.

Theories abound over what that something could have been, with explanations both prosaic (meteorite or comet) and preposterous (UFO crash, one of Tesla’s experiments gone wrong) offered over the years since that mysterious event. While I personally love the idea of a UFO crash, it turns out that scientists working with the Russian Academy of Science may have turned up the first solid proof that a meteorite may have been the actual culprit:

Via Technology Review:

In the 1930s, an expedition to the region led by the Russian mineralogist Leonid Kulik returned with a sample of melted glassy rock containing bubbles. Kulik considered this evidence of an impact event. But the sample was somehow lost and has never undergone modern analysis. As such, there is no current evidence of an impact in the form of meteorites.

That changes today with the extraordinary announcement by Andrei Zlobin from the Russian Academy of Sciences that he has found three rocks from the Tunguska region with the telltale characteristics of meteorites.
