Scientists say they have found the first evidence of a supernova explosion found on Earth. The researchers came to this conclusion after carefully studying the extraterrestrial Hypatia stone found in Egypt in 1996, Science alert reports..

The chemical composition and structure of the rock indicated that this rock contained traces of dust and gas that surrounded a Type Ia supernova.. Such explosions are the most energetic events in the universe, they happen when a dense white dwarf engulfs another star..

According to scientists, over billions of years, dust and gas solidified, forming the mother body from which Hypatia, which is the same age as the solar system, arose..

The sample contains unusually low levels of silicon, manganese and chromium, indicating the rock was not formed in the inner solar system, the researchers said.. Scientists have also recorded high levels of iron, sulfur, phosphorus, copper and vanadium, which is also evidence that the object was formed in deep space..

Analysis of the elements of Hypatia indicated that their composition is different from that which could form in rocks inside the solar system or in our arm of the Milky Way.. Scientists have also dismissed the idea that the parent body formed from the remnants of a red giant..

Scientists also found that the composition of Hypatia does not correspond to indicators that could indicate that its progenitor was a type II supernova, it has too much iron compared to silicon and calcium, so it is most likely that the object appeared as a result of a type II supernova explosion..

Such explosions should produce an interesting combination of elements in rocks similar to those recorded at Hypatia.. Scientists analyzed 15 elements, some of which correspond to rock formed as a result of the explosion of a dense white dwarf. But six elements don't match a Type Ia supernova explosion.. Scientists believe that an event that occurred in the distant past of the existence of a star can explain their presence..

Earlier, astronomers from the University of Florence announced that they managed to find traces of the first stars that appeared in the Universe.. It is likely that their elements contain the star AS0039, which is located in the dwarf galaxy Sculptor at a distance of 290 thousand light years from Earth..
