Explanation

Voyager 1 and Voyager 2 were launched in 1977 to explore the outer planets. Voyager 1 crossed the heliopause (the boundary where the Sun's solar wind is stopped by the interstellar medium) in August 2012, becoming the first human-made object to enter interstellar space. Voyager 2 followed in November 2018. Both spacecraft continue to transmit data and are expected to operate until at least 2025.
