Unusual Meteorite Glided Around in Space before the Earth was Born. Around 4.5 billion years ago the cataclysmic explosion of an enormous star a supernova resulted in an expansive cloud of cosmic dust and gas to gather and form our solar system. But precisely how the planets were built remains an enigma to the scientists.
Presently a contemporarily found 4.6-billion-year-old, glittery green meteorite that was composed just prior to the outburst is assisting scientists educate more about how the solar system’s planet assembled together.
The extraordinary baseball-size space rock, called Northwest Africa (NWA) 11119 was obtained by a meteorite dealer in Africa in 2016. The dealer sent the sample to Carl Agee, a planetary geologist and meteorite curator at the University of New Mexico. Agee was not sure if the rock was a meteorite so he approached Poorna Shrinivasan to inspect the object.
Initially both Agee and Srinivasan were doubtful that the rock came from the far side of our planet. Srinivasan said that we did not accept that this rock was a meteorite at all. They thought it belonged to the Earth. However, succeeding a closer inspection we observed that it was evident enough of not belonging to Earth. While the rock mirrored many volcanic rocks, its chemical composition signified that it was undoubtedly from space and it was definitely not a usual meteorite.
NWA 11119 is an ingenious meteorite which means it was devised by the cooling and solidification of magma or lava. At 4.6 billion years old, NWA 11119 is the most ancient igneous meteorite ever found.
