Origins of the Solar System Marabella Productions

PBS NOVA scienceNOW
Did an ancient supernova explosion trigger the birth of the solar system? Scientists are finally closing in on evidence that, nearly five billion years ago, a supernova shock wave swept through a cloud of dust and gas and caused it to collapse, eventually forming the sun and the planets. Meteorite hunters have scoured the globe for space rocks containing evidence of this ancient supernova in the form of rare isotopes that could only be created in the intense pressure of a supernova explosion. Working side-by-side with computer modelers, who create dazzling visual simulations of the baby solar system, they have revealed that the death of an enormous star, at least twenty times the mass of our sun, could be responsible for the birth of our own solar system. We also see amazing Hubble images of nebulae where the same cycle is happening today.
