Scientists believe that the solar system exists because of a lucky coincidence. A nearby supernova could have destroyed it, but it didn't.
The assumption of a supernova explosion 4.6 billion years ago has been linked to the discovery of additional radioactive aluminium in the solar system. Scientists believe that our star system survived the explosion due to the molecular gas that took the hit and coincidentally became the shield by which you and I exist.
Here's What We Know
It is believed that meteorites falling to Earth allow scientists to study the evolution of the universe. At the dawn of the Solar System, a star exploded nearby and became a supernova. Scientists decided this after examining isotopes of elements from meteorites.The assumption of a supernova explosion 4.6 billion years ago has been linked to the discovery of additional radioactive aluminium in the solar system.
