The origin of the Supernova involves a great explosion. However, it does not have only destructive consequences. In fact, the dying of one star creates a life of another one and additionally, it gives life to novel chemical elements.
About 2 million years ago, a grand explosion of such star has happened closely to our solar system. There have been found multiple pieces of evidence of this happening on the Earth thanks to iron. This process significantly enhanced the concentration of iron, which has been found in the Pacific Ocean.
How does it prove the origin of Supernova? Well, the radioactive 60Fe isotope could not be created on our planet. This is an exclusive consequence of explosion in the space. In addition, the age of this isotope is over 2.62 million years, which is older than our planet. Therefore, its birth has occurred in the space and afterward, appeared on the Earth. There are no other places on the planet where people could find anything similar to this isotope.
Lunar samples from the Apollo missions
The first theory of supernova origin appeared in the year 1999. It has become utterly popular at once and nowadays, more and more novel studies pay great attention to this matter. The first claim of supernovae hypothesis was put forth by the Technical University of Munich. Afterward, a great and fruitful collaboration with the U.S.A. showed another intriguing fact. The presence of this radioactive isotope was detected on the surface of the moon.
The evidence was gathered in the periods of 1969-1972 by the mentioned above Appolo missions. The missions 12, 15 and 16 brought back to the Earth the real samples of this material. This makes sense because the moon is quite close to our planet and while the bombardment, some parts of the exploded star could reach the surface of the moon.
However, the pieces found on the moon did not break, as the atmosphere of our planet and the moon are different. They fell there undamaged and were not deformed. Then they underwent a transmutation process. Nonetheless, the scholars say that the amounts of those samples are not enough to build a dependable theory. The further studies should shed more light on this matter.
Deposits of newly produced stellar matter
Dr. Korschinek, the head of the research, said that both samples found in the Pacific and on the moon have the same origin, which is the result of newly created stellar matter.
The moon greatly helps the space explorers to discover different things about our system, its planets and the heavenly bodies in other galaxies. The moon has a better cosmic record than our planet. In the case of the 60Fe isotope, it helped to define the upper limit of this element. This contributed to the discovering of the distance that took for the Supernova. The scholars determined that it took approximately 300 light years from the star to reach our solar system. This theory is mostly accepted by all experts in this sphere.
All the extracted lunar samples of this element were examined with the assistance of the high-sensual accelerator mass spectrometer of the Maier-Leibnitz Laboratory near Munich. They are considered to be true.
