New Theory Proposed for Solar System Formation - Universe Today
A new theory from researchers at Arizona State University challenges the traditional view of the formation of our Solar System. Instead of forming within an out-of-the-way cloud of interstellar gas and dust, they believe we formed in the intense environment that typically creates more massive stars. The core of their argument is the recent discovery of iron-60 in meteorites; this isotope can only be found in the heart of massive stars. This could mean that the Sun formed while a more massive star was nearby, blasting our environment with intense ultraviolet radiation.
