CTOnews.com July 28 news, astronomers recently discovered the first ever "boomerang meteorite"(boomerang meteorite), the stone originated from the earth, presumably 10,000 years ago in an asteroid impact or volcanic eruption from the earth ejected into space, and then returned to earth.

The meteorite, named NWA 13188 and weighing 646 grams, was discovered by scientists at the University of Aix-Marseille in France after in-depth study and found to have many characteristics of Earth rocks.

The analysis found that the meteorite not only has the composition found in the crust and volcanic rocks, but also has elements that only appear after long-term exposure to high-energy cosmic rays.

Meteorite hunters discovered the rock in question in Morocco in 2018 and scientists named it Northwest Africa (NWA).

The analysis, led by Jérôme Gattacceca, determined that the rocks had the "bulk basaltic andesite composition" found in volcanic rocks on Earth.

Gattacceca and his team found isotopic signatures such as beryllium-3, helium-10 and neon-21 in NWA 13188.

CTOnews.com translated Gattacceca as follows: "There are indications that NWA 13188 came from Earth and returned to Earth after staying in space." If confirmed, NWA 13188 would create a type of boomerang meteorite that some geologists call "terrestrial meteorites."
