Scientific experts have looked back at the past of our planet, revealing that rare meteorites from a million years ago still shower Earth. Philipp Heck, a cosmochemist at the University of Chicago and also a curator of meteorites for the Field Museum, decided to be one of the scientists who prefer to look at the past of our solar system, unveiling new things.
He has looked at the L-chondrite meteorites which were dispersed to approximately 99% part of the planet. Heck analyzes the ‘collision cascade’ which was discovered to have significant effects on our planet with all its crashes and smashes. Statistics show that this cascade of meteorites happened about 455 million years ago when the continents were not yet formed.
They were only a massive land. Nevertheless, a million years later, the meteorite shower continues to affect the planet, keeping on falling even after the area divided to form the continents we know today. Some researchers decided to analyze the L-chondrite meteorites no longer, revealing that there was no evidence to attest the truth of the events which happened during the meteor shower.
What is more, L-chondrite meteorites do not all stand for the primary composition of the asteroid belt. On January 23, specialists report that Phillip Heck developed a new study which was published in the Nature Astronomy magazine. This newly developed research is bound to adopt a different perspective to further look deeper at the composition of space particles.
After specialists had analyzed the Ordovician period which represents the timespan before the collision cascade of the L-chondrite meteorites, they have unveiled that ungrouped space particles and achondrites were more pervasive compared to nowadays. Heck decided to perform some laboratory test bound to analyze minerals, studying their chemical composition.
Thus, he together with his team was able to differentiate between one space particle and another. The team has analyzed the composition of 43 rare meteorites which reached Earth approximately 470 million years ago. This discovery will help them build a new path, step by step, heading towards where and what type of meteorite it emerged from, but also how long it will take these space particles to reach our planet. The new findings will definitely help them uncover the mysteries related to meteorites.
