in 2011, Mysterious fragments of an unknown rock that fell to earth billions of years ago have been discovered in western Sahara in Morocco. Today, researchers have just revealed the story of its creation.

It contains tiny fragments that are almost 4.5 billion years old. nicknames” black Beauty ‘, that dark looking rock was first found in 2011 in the Desert the Sahara, in Morocco. Approximately ten additional samples were then taken from the same parent rock. Since then, scientists have determined the origin of this mysterious rock: it comes from our neighboring planet Mars. But the story that brought it to us was missing to this day: an international collaboration of researchers managed to reconstruct it in a study published in the journal type communication.

Nearly 90 million craters identified

Black Beauty is composed of his real name NWA 7034 martian rock very old, 4.5 billion years old. So it was formed in the early days of the solar system, while the continental crust, as the name suggests, forms the continents. It’s essentially a…” data-image=”” data-url=”” data-more=”Read more”>earth crusts and Martians weren’t done yet. Exactly where it comes from remains to be seen. For this, the researchers used a supercomputer are used, among other things, to create weather forecasts, study the climate, create models …” data-image=” /buildsv6/images /midioriginal/6 /c/1/6c1f36320a_81309_supercomputer.jpg” data-url=”” data-more=”Read more”>supercomputerwhich analyzed thousands of images of the surface of Mars thanks to an algorithm machine learning. In all, the team identified nearly 90 million impact craters, including the crater where Black Beauty originated: Karratha Crater, named after an Australian town that is home to one of the oldest rocks on earth.

5 to 10 million years ago, a asteroid impact created the Karratha crater, and many fragments of the Martian crust were hurled into space. Including Black Beauty, which actually corresponds to a collection of more or less old fragments of the Martian crust. “Locating the region of origin of the Black Beauty meteorite is critical because it contains the oldest Martian fragments ever found, which are 4.48 billion years old, and shows similarities to the very old Martian crust, which is 4.48 billion years old is.” about 4.53 billion years ago, and the continents of present-day Earthenthused Dr. Anthony Lagain, first author of the study and a researcher at Curtin University.
