The Mars meteorite nicknamed "Black Beauty" may contain references to the history of the Red Planet



The meteorite weighs about 11 ounces and is estimated at 4.4 billion years.

A thick, black chunk of rock no bigger than a baseball may contain clues to the four and a half billion years history of Mars, Outer Places reports.

"Black Beauty" (or better officially, NWA 7034) was found in 2011 in the Sahara. There is absolutely nothing special for the untrained eye: It's black (of course), more or less smooth on one side, is about the size of a baseball and weighs 320 grams (about 11.29 ounces) – about the weight of one Can of soda. However, to hold it in your hand, you have to hold a time capsule containing the secrets of the history of the solar system.

Why is it important?

"Black beauty" is what geologists call a breccia ̵

1; that is, it consists of different types of rocks fused together by heat. This is important, because it means that the rock comes from the Martian crust, as other known Martian meteorites that came from the surface.

With the help of chronometry – ie the science of age measurement – scientists determined the rock is 4.4 billion years old.

All in all, this means that scientists are now gaining new insights into how the crust of the Red Planet has formed. In particular, there is evidence of what astronomers call the "Mars dichotomy" – that is, the differences in terrain between the northern and southern hemispheres of Mars.

Cosmochemist Bill Cassata says the rock is an indication that Mars' dichotomy is well advanced earlier than previously thought.

Everything else is cool about "Black Beauty"

Yes, indeed: In 2013, as NASA reported at that time, scientists found something amazing about This particular Mars stone: it contains water, in fact it contains 10 times more water than any other known Martian meteorite, which is a pretty conclusive proof that water was suddenly on Mars.

Wait, Other Martian Meteo Rites?

Black Beauty is not the only Martian meteorite found on Earth, in fact, according to The Meteoritical Society, there were 132 confirmed Martian meteorites found on our planet in recorded human history And wondering how the scientific community has confirmed this, no longer wonder: According to a 2013 NASA report, the Curiosity Rover performed an analysis of argon in the Martian atmosphere to determine the Martian origin of these meteorites here to confirm on earth [19659003] How did you get here?

Violent. The prevailing theory is that the rocks were ejected from the planetary surface by impacts from comets or asteroids. Then they traveled millions of miles through space, survived the dangerous journey through our atmosphere, and then some lucky ones managed to land on solid ground where humans could find them.
