Low-mass star explosion drove solar system formation: Study
According to Minnesota-based researchers, formation of the solar system may have been triggered by a low-mass supernova explosion. Examining meteoritic records, the researchers found an abundance of radioactive Beryllium-10, an element that is believed to be formed by a process called 'neutrino spallation' in supernovae. The explosion caused a dust-and-gas cloud to compress into the solar system.
