Voyager 1 is a space probe launched by NASA on September 5, 1977, to study the outer planets of our solar system. It made significant discoveries during its flybys of Jupiter and Saturn, providing valuable data about their atmospheres, moons, and rings. Currently, Voyager 1 is the most distant human-made object from Earth, having entered interstellar space in 2012. It continues to send back data about cosmic rays and magnetic fields, helping scientists understand the environment beyond our solar system and the nature of interstellar space.
