The NWA 13188 meteorite, which was found in Morocco in 2018, is said to be “the first meteorite in history that comes from the Earth itself,” as opposed to previous meteorites that are believed to come from other planets.
This was presented in an international study at the Goldschmidt Conference of the Geochemical Society, which took place in Lyon, France, from July 9 to July 14, 2023, according to Hespress AR. The study revolves around the meteorite NWA 13188, which fell in the Moroccan desert in 2018.
The study found that the NWA 13188 meteorite, “was ejected from Earth by a collision with an asteroid or a volcanic explosion thousands of years ago, spent an average amount of time in space before returning to Earth, precisely to fall in Morocco”.
As a result, NWA 13188 would be the first meteorite to ever come from Earth, but this remains unconfirmed given the researchers’ lack of an accurate astronomical calculation of the meteorite’s travel time.
It was determined through careful investigation that the meteorite “has the same chemical compositions as the volcanic rocks on Earth, and it has been exposed to cosmic rays in space for up to ten thousand years.”
Participants and scientists at the meeting expressed surprise and queries in response to the researchers’ disclosure of this information.
“This meteorite was launched from the earth before it bounced back in space to return again and be discovered in the Moroccan desert,” according to the scientists.
examination of the NWA 13188 meteorite revealed that it is “a vesicular igneous rock with a comprehensive basaltic composition, and a sub-woolly texture, dominated by plagioclase and pyroxene.
The 650 kilogram meteorite is predicted to become the first-ever “terrestrial meteorite” if the presumptions made by the researchers are correct.
Scientists asserted that “the possibility of forming Earth rocks on other planets is very possible in our current solar system.”
Morocco is well known for the fall of rare meteorites, including the Martian meteorite Tissent, which was discovered in 2011 and which had previously shown an unprecedented diversity of organic compounds, which opened speculation about the existence of previous life on Mars.
