Curious find at the Chelyabinsk event.
Research has been published reporting the discovery of a type of crystals "never seen before" that were hidden in small grains of meteoric dust left behind by the space rock that exploded over Chelyabinsk in Russia in 2013.

The interesting thing is that when it exploded, the entire area was pulverized and bathed with small meteorites, mostly the size of dust, which ultimately turned out very well because it avoided a direct impact with the surface, although unfortunately there was also damage and injured, in fact, experts say that this explosion is the largest that has occurred on earth of a meteoric origin since the Tunguska event in 1908.

The impact did not leave a block of the fireball, it was pulverized and luckily there are small fragments that have been recovered and with them a new study has been carried out where the researchers analyzed these small fragments that remained after the Chelyabinsk meteorite exploded, generating a huge column of dust that remained suspended in the atmosphere for more than four days before finally falling to earth.

These curious crystals have two forms, an almost spherical shell shape, and others that are shaped like hexagonal rods, the scientists did an x-ray analysis that revealed that the crystals were made of layers of graphite, graphite is a form of carbon made with overlapping sheets of atoms, graphite is found in everyday pencils, but curiously, it is also the one used to create graphene; investigations will continue to reveal whether these crystals were formed by the impact or were already formed.
