Mysterious pebbles were found in the Egyptian desert is the first definitive evidence that the comet had hit the Earth. It was revealed after the South African researcher team conducted a series of analyzes of the nucleus of comet stones were found in 2012.

"This is a typical scientific euphoria when you eliminate all other options and recognize the fact that it should," said the author and study leader, Jan Kramer of the University of Johannesburg in South Africa, as quoted from Space, on Wednesday, October 9, 2013.

The pebbles was given the name "Hypatia", in honor of the ancient female mathematician, astronomer, and philosopher, Hypatia of Alexandria. The stone that encrusted with diamond, something that makes sense considering the origin of comets. "Diamonds are produced from carbon-containing materials," said Kramer.
"Usually they are formed deep within the Earth, in a high pressure, but you also can result in a very high pressure through the shock. When comets collide, shocks in the colliding could produce diamonds."
It's very hard collision occurred about 28 million years ago in the Egyptian, according to one of the researcher team members. Comet exploded in the atmosphere, heating the sand beneath it to a temperature of 2,000 degrees Celsius, and yellow silica glass produced in an area of 6,000 square kilometers in the Sahara Desert. Even the silica glass stones decorate the brooch which owned by the famous Egyptian pharaoh, Tutankhamen.
Comets almost certainly hit the Earth many times during the long history of this planet. But before the advent of Hypatia black pebbles, small dust particles in the upper atmosphere and carbon-rich dust in Antarctic ice comet is the only material known on The Earth. The study will be published in upcoming issue of Earth and Planetary Science Letters. *** [EKA | FROM VARIOUS SOURCES | SPACE | METRO | ERWIN Z | KORAN TEMPO 4370]
