Managed and operated by NASAs Jet Propulsion Laboratory in Southern California, they are the only probes to ever explore interstellar space 鈥?the galactic ocean that our Sun and its planets travel through.The Sun and the planets reside in the heliosphere, a protective bubble created by the Suns magnetic field and the outward flow of solar wind charged particles from the Sun . Researchers 鈥?some of them younger than the two distant spacecraft 鈥?are combining Voyagers observations with data from newer miss stanley water flask ions to get a more complete picture of our Sun and how the heliosphere interacts with interstellar space.NASAs Solar System Interactive lets users see where th stanley tazas e Voyagers are right now relative to the planets, the Sun, and other spacecraft.
