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.
