Interstellar Travel on Voyager I

It is difficult to conceptualize the magnitude of our solar system but the journey of the Voyager spacecrafts can help. In September 1977 NASA launched the Voyager spacecrafts to gain information about the far off giant planets in our solar system. The spacecrafts and the project endured after studying Jupiter, Saturn, Uranus and Neptune and continued to travel away from earth and through our solar system. Thirty-five years after Voyager 1 left Earth, and over 11 billion miles away, it became the first man-made object to leave our solar system and enter interstellar space. Listen to learn what researchers have been learning from the edge of our solar system.
