Scientists have been searching for the mineral for a long time, because in order to identify a mineral one must know its chemical composition and crystal structure, Ma said.
Researchers found the bridgmanite in a meteorite that had fallen to Earth near the Tenham station in western Queensland, Australia, in 1879.
The meteorite, Ma said, is highly shocked, meaning it endured high temperatures and pressures as it slammed into other rocks in space. Those impacts can create shock veins of minerals within the meteorites.
"Scientists have identified high-pressure minerals in its shock-melt veins since 1960s. Now we have identified bridgmanite," Tschauner said, referring to the Tenham meteorite.
The meteorite is considered a chondrite, the most common type of meteorite found on Earth; scientists think these meteorites are remnants shed from the original building blocks of planets.
Most meteors (which are called meteorites once they strike Earth) are fragments of asteroids, while others are the cosmic dust discarded by comets. Rarely, meteorites represent impact debris from the moon and from Mars.
