According to new research, our bones and teeth were formed as a result of the explosion of calcium-rich extremities and the release of large amounts of calcium into the universe.
As the famous astronomer Carl Sagan said, "We are all made of star dust."
Half of the calcium in the universe comes from calcium-rich extremists, Qadin.Net reports citing publika.az. However, this phenomenon is very rare, so it is very difficult for scientists to observe and analyze it.
It is known that as a result of the explosion and collision of stars, heavy elements such as gold and platinum are formed. But calcium is more mysterious.
The situation changed after a tip from an amateur astronomer, a global group of 70 astronomers from different countries was formed, and the results of the study were published in the August issue of the Astropysical Journal.
In April 2019, Joel Shepherd observed a bright explosion and a bright orange dot while observing the Messier100 spiral galaxy, 55 million light-years from Earth, through his telescope, and then reported the event to the astronomical community. Following the news, telescopic observations of the object began from around the world. Thus, the telescopes of the Swift Orbital Observatory, the Leak Observatory in California and the Cake Observatory in the Hawaiian Islands, which can be remotely controlled by researchers from Northwestern University, are aimed at this object called SN2019ehk.
According to Vin Jacobson Gala, "The observation of the extremist a few hours after the explosion is a new phenomenon. The discovery of such a very young iftaty as an emerging object allows us to obtain information about the last moments of the star's evolution immediately before the explosion.
Calcium-rich extreme
According to Jacobson, "Stars that are candidates for a calcium-rich extremity have been throwing matter in layers in the last months before the explosion." The collision of the explosive substance causes X-rays.
According to the researchers, the heat and pressure created during the explosion trigger a chemical reaction that results in the production of calcium.
Usually, each star produces a small amount of calcium as a result of the combustion of helium. However, when calcium-rich extremes occur, large amounts of calcium are formed several times within seconds after the explosion.
"The explosion is trying to cool down," says Rafaella Margutti. He wants to give his energy to the environment, and the release of calcium is the most effective way to do that. ”
Jacobson Qalan said the incident was caused by a hot air balloon trying to balance with the environment after the explosion. Nature chooses the path of the weakest resistance, and the extreme easily provides this path when it has enough calcium. "
Although the Hubble Space Telescope has observed the galaxy for 25 years, it has not recorded a star that has become extreme. Scientists explain this by the fact that the star is very weak, or has a bare nucleus, or is very small in mass. If it weren't for the explosion, it would be unknown if there was a star there, because Hubble couldn't even see it. It is possible that this is a characteristic of calcium-rich extremists, in contrast to extremes formed from massive stars. This makes it difficult to detect calcium-rich extremities far from Earth. In the future, it is planned to conduct research with telescopes that can detect more extremes. This is part of the plans of the soon-to-open Vera Rubin Observatory.
According to scientists, in such extreme stars, there must be instability, which results in the throwing of the upper layers before the explosion. Researchers are working to study how the extremity evolved after the explosion. They also focused their research on X-rays, which were unexpected until this observation. The research team (very new and gloomy or weak) is looking for a method that can detect ultra-candidate stars so that short-term post-explosion X-rays can be recorded with spacecraft.
