"This impact occurred about 28 million years ago over Egypt, study team members say. The comet exploded in the atmosphere, heating the sand below to a temperature of 3,630 degrees Fahrenheit (2,000 degrees Celsius) and generating huge amounts of yellow silica glass across 2,317 square miles (6,000 square kilometers) of the Sahara Desert.Another example of how science and humanities can intersect and how they needn't ever be mutually exclusive.
"One piece of this silica glass even found its way into a brooch that belonged to the famous Egyptian pharaoh Tutankhamen, researchers said.
"Comets have almost certainly struck the Earth many times over the planet's long history. But before the Hypatia pebble's origin was determined, tiny dust particles in the upper atmosphere and carbon-rich dust in Antarctic ice were the only cometary material known on Earth, researchers said."
