Voyager 1 was launched by NASA on September 5, 1977, and is one of the most significant achievements in space exploration. Its mission began with a flyby of
in March of 1979, where it captured unprecedented images of the planet's atmosphere and discovered
on its moon
- marking the first observed volcanic activity beyond Earth, itself.
Continuing its journey, Voyager 1 reached
in November of 1980, studying its
and atmosphere and providing detailed data on
, the planet's largest moon, which was found to have a dense, nitrogen-rich atmosphere. After that encounter, Voyager 1 was directed out of the plane of the Solar System, bypassing the seventh and eighth planets,
and
, which were later visited by its twin, Voyager 2.
As it traveled farther from the Sun, Voyager 1 entered the

- around 2004, where the
slows down due to interaction with interstellar particles. On August 25, 2012, it crossed the
, officially entering
, becoming the first human-made object to do so. Despite the vast distance - over 20 billion kilometers (12.4 billion miles) from
- Voyager 1 continues to transmit data, although its instruments are gradually shutting down due to limited power.
Voyager 1 also carries the
, a phonograph disc containing sounds and images representing Earth's culture and diversity, intended as a message to any
it might encounter. Its journey not only expanded our understanding of the outer planets and the edge of the solar system but also symbolized humanity's enduring curiosity and desire to explore the cosmos.
