Scientists Say 'Little Bang' Caused Formation of Solar System
For several decades, scientists have thought that the Solar System formed as a result of a shock wave from an exploding star - a supernova - that triggered the collapse of a dense, dusty gas cloud that contracted to form the Sun and the planets. But detailed models of this formation process have only worked under the simplifying assumption that the temperatures during the violent events remained constant. Now, astrophysicists at the Carnegie Institution's Department of Terrestrial Magnetism (DTM) have shown for the first time that a supernova could indeed have triggered the Solar System's formation under the more likely conditions of rapid heating and cooling. - Carnegie Institution for Science Scientists Say 'Little Bang' Caused Formation of Solar System
