Dr. Kent Montgomery, director of the Texas A&M-Commerce Planetarium, says Voyager I has left the solar system, soon to be followed by Voyager II. Voyager I was launched in 1977, so NASA has received 40 years of data and photos from the spacecraft, much more than expected. Dr. Montgomery says Voyager II has provided the only close up pictures of Uranus and Neptune. The spacecraft will continue traveling through the universe and sending back data, but at some point the signal will become too weak to be detected.
