According to SPACE, radioisotopes in meteorites indicate that a supernova erupted near the solar system during its formation. A supernova explosion approached our newly formed sun and would have destroyed the solar system – if not for a shield of molecular gas. Scientists reached this conclusion by studying isotopes of the elements discovered in meteorites, and these space rocks are fragments of asteroids formed from materials that were present during the formation of the sun and then the planets of the solar system, in this way, meteorites are formed. There are fossils that allow scientists to reconstruct the evolution of the solar system. The research team found different concentrations of a radioactive isotope of aluminum in meteorite samples, and these data showed that regarding 4.6 billion years ago, an excess amount of radioactive aluminum entered our planet’s backyard. Study team members said the best explanation for such an injection of radioactive material is a nearby supernova explosion. According to these researchers, led by Japanese astrophysicist Doris Arzumanian of the National Astronomical Observatory, the nascent solar system may have survived the supernova explosion wave, adding that the cocoon of the birth of the solar system most likely acted as a barrier once morest this shock wave. Supernovae explode when massive, dying stars run out of fuel for nuclear fusion and their cores can no longer support themselves once morest gravitational collapse. This material becomes the building blocks for the next generation of stars – but the blast wave it sends out can be powerful enough to rip apart any newborn planetary systems that happen to be nearby. Stars are born in giant clouds of molecular gas made up of dense filaments, or filaments. Smaller stellar bodies, such as the Sun, form along these filaments, while larger stars, such as those that may explode in this supernova, tend to form at points. where these intersect. With this in mind, Arzumanian and the research team estimated that it would take regarding 300,000 years for the supernova shock wave to tear apart the dense filaments protecting the infant solar system.
