From the caption:
In 1977, NASA’s twin Voyager spacecraft embarked on an incredible journey to the outer planets and beyond. After delivering stunning images of Jupiter, Saturn, Uranus and Neptune, the probes sailed on to study the boundary of our heliosphere, the bubble that encompasses our sun, planets and solar wind. Voyager 1 crossed that frontier in August 2012, becoming the first human-made object in interstellar space, while Voyager 2 is expected to enter the space between the stars in the coming years. This live public talk at NASA’s Jet Propulsion Laboratory in Pasadena, California, revisits highlights of the last 40 years and discuss what may lie ahead for the intrepid Voyagers.
