A rock found on the Moon was tested by scientists and is said to come from another planet this week. Our planet is more than likely. But how did a piece of earth get to the moon, and what did I hear about our planet and our moon being made of the same material? The origin of this rock, regardless of its origin, can be traced back to antiquity on the basis of its petrographic and chemical characteristics. Both are consistent with the educational conditions "usually associated with both the lunar and the land environment."
The differences between the rocks on our moon and rocks on our earth are weak. They are so small that the average viewer usually has no chance to distinguish one stone from the other ̵
There, the researcher headed a new research project, J.J. Bellucci showed evidence of the first terrestrial meteorite ever discovered – on our moon or anywhere else. The rock was first brought by the crew of Apollo 14, the eighth man-controlled mission in the US Apollo program, from our moon and the third ever landed on our planet's own moon.
So, what these researchers suspect is, in fact, the Apollo 14 astronauts (back in February 1971) traveled all the way to the Moon to collect stones, one of which was created on Earth. They can now be described as the largest team of rock retrievers of all time.
An extensive collection of materials has been picked up by various Apollo missions to the Moon and brought to Earth in recent decades. The fact that this particular sample has not been thoroughly studied so far is not irregular. For example, consider the nearly three decades of storage between the accumulation of grime from the T.rex bone environment called Sue and the eventual discovery of tiny little shark teeth (just reported last week). There are many rocks that need to be closely examined by the Moon and from here on Earth.
The difference between rocks of the earth and rocks that were in space or on the moon (19459009) can be seen in the state of the rockitic volcanic rock inside. There is evidence that the rock either comes from the depths of the topmost layers of the moon, or has formed on the earth, and had been ejected into outer space from the surface of our planet and landed on our moon earlier in antiquity.
The likelihood that this rock is formed below the surface of the moon is less likely, mostly because such a hypothesis is not responsible for the "high degree of crystallization" of the sample. The alternative to this hypothesis – one from Earth – reads as follows:
"Alternatively, the rockite and its zircon crystallized on the earth at a modest depth of 19 ± 3 km in the continental crust where oxidizing, low -T fluid conditions are common, "write the authors of the published research paper this week. "Subsequently, the clone was ejected from the earth during a large impact and carried as an earthly meteorite into the lunar regolith, with the indication that the conditions were reduced during installation in the host's imbrium ejecta and breccia."
Otherwise, this rock probably formed between 4.0 and 4.1 billion years ago. It is old, very old.
