The Martian meteorite is estimated to be 4.5 billion years old.
, meaning it contains angular fragments of multiple rock types cemented together. In contrast, all other known Martian meteorites contain single rock types.
Until now, scientists did not know precisely where on Mars NWA 7034 came from. Now, researchers may have pinpointed Black Beauty's exact point of origin. In the new study, the scientists used supercomputers to analyze images of the Martian surface."My team and I developed a crater-detection algorithm to detect all impact craters, down to about 100 meters [330 feet] in diameter, seen on high-resolution images covering the surface of Mars, about 94 million in total," study lead author Anthony Lagain, a planetary scientist at Curtin University in Perth, Australia, told Space.com.
When the researchers investigated the sizes and locations of these craters, they realized that most of the smallest craters were scattered around larger craters that were more than 1.8 miles wide and less than 10 million years old. These findings suggest that these small craters were formed by the debris from larger impacts after they fell back to the surface.
