These jets occurred before and during the formation of our solar system, possibly driving the explosion of the supernova that formed our solar system. They also accompany the death of stars, including the eventual demise of our own Sun. Cosmic jets fill the space between galaxies with high-energy particles and may be responsible for generating most of the magnetic energy in the universe. Black hole formation also can lead to the formation of these jets and ultimately trigger a gamma-ray burst, the most powerful object in the Universe. This presentation will focus on cosmic jets and how this spectacular phenomenon is an integral part of our origins and in the structure and evolution of the Universe.
