The 16-Billion-Mile Journey Of Humanity's Farthest Object

In 1977, humanity launched an impossibly ambitious mission to the outer edges of the solar system: the Voyager twin spacecraft. Made possible by a rare 176-year planetary alignment, this fragile 1970s engineering survived lethal radiation and broken parts to capture a final portrait of our universe. While the original documentary noted Voyager 1 crossing into interstellar space at 11 billion miles away in 2012, it has continued its relentless pace and, today, this incredible machine is over 16 billion miles from Earth.
