Our solar system is probably a remnant of a massive supernova explosion

Signs of a supernova

The research group found various concentrations of the radioactive isotope of aluminum in the meteorite samples. Based on this information, about 4.6 billion years ago, more radioactive aluminum entered our planetary range. The best explanation for the injection of this amount of radioactive material can be a nearby supernova explosion. In other words, the birth cocoon of the solar system has acted like a protective curtain against this shock wave.

Supernova explosions usually occur when dying massive stars reach the end of their nuclear fuel supply and their cores can no longer prevent the star from collapsing. With the collapse of the core, a supernova begins, which scatters the heavy elements of the star into space.

Supernova material is the building blocks of the next generation of stars, but the blast wave they carry with them can be powerful enough to destroy any newborn planetary systems nearby. Stars are born in massive clouds of molecular gas that are a mixture of dense tendrils and filaments. Smaller stellar bodies, such as the Sun, form along these filaments, while larger stars, such as a star that explodes as a supernova, are usually born at the intersection of the filaments.
