NASA's Voyager 1 probe has become the first man-made object to enter interstellar space, the U.S. space agency announced Thursday.
Scientists report they have strong evidence that the unmanned spacecraft has crossed the magnetic boundary separating the solar system's sun, planets and solar wind from the rest of the galaxy. The announcement comes more than 36 years after the unmanned spacecraft lifted off on a journey that gave humans close-up views of Jupiter and Saturn before heading toward deep space.
