More than four decades after beginning its epic journey, NASA’s space probe Voyager 2 has crossed the elusive boundary that marks the edge of the Sun’s realm and the start of interstellar space, scientists have announced. Now, it has become the second human-made object in history to reach the edge of our solar system.
