NASA: Voyager 2 spacecraft reaches interstellar space after four decades exploring solar system
NASA's Voyager 2 probe, launched in 1977, is now more than 11 billion miles from Earth and has reached interstellar space, the agency said Monday. This is the second time a human-made object has reached this part of space. And it's an incredible feat for a spacecraft designed to last five years. Voyager 2 is now NASA's longest-running mission, with 41 years under its belt.
