This story is a part of Welcome to Mars, our collection exploring the pink planet.
The “Black Magnificence” Mars meteorite is a marvel. It was discovered on Earth within the Saharan Desert in 2011 and given the official identify Northwest Africa (NWA) 7034. It earned its nickname from its darkish look. Very like a superhero, the meteorite has an origin story, which has now been revealed due to a supercomputer and a world staff of researchers.
We knew Black Magnificence’s dwelling planet. Now we all know its dwelling crater the place it bought yeeted off Mars by an asteroid impression someplace round 5 million to 10 million years in the past. Fortunate for scientists, it landed on Earth.

A examine revealed on Tuesday within the journal Nature Communications particulars the work of a machine studying algorithm working on a strong supercomputer on the Pawsey Supercomputing Analysis Centre in Australia.
The supercomputer analyzed a staggering 90 million impression craters seen in Mars photos to find the crater that produced Black Magnificence. A comparability of the age and properties of the meteorite to the craters pointed to only one matching website. The staff named the crater Karratha after a metropolis in Australia.
There was an enormous give attention to the seek for indicators of historical microbial life on Mars, however the planet may also train us concerning the younger days of our personal world. “The area we determine as being the supply of this distinctive Martian meteorite pattern constitutes a real window into the earliest surroundings of the planets, together with the Earth, which our planet misplaced due to plate tectonics and erosion,” mentioned lead writer Anthony Lagain in a Curtin College assertion Tuesday.

Preliminary analysis dated Black Magnificence to 2.1 billion years in the past. One other look discovered that some materials within the rock dates again almost 4.5 billion years. The meteorite is necessary for its composition in addition to its age. “Black Magnificence is the one brecciated Martian pattern out there on Earth, that means it accommodates angular fragments of a number of rock sorts cemented collectively which is totally different from all different Martian meteorites that include single rock sorts,” mentioned Curtin.
Within the examine, the researchers counsel Black Magnificence’s hometown could possibly be a great goal for exploration. “This province is a perfect touchdown website for future missions aiming to unravel the primary tens of hundreds of thousands of years of the historical past of Mars and, by extension, of all terrestrial planets, together with the Earth.”
