The Voyager 1 spacecraft, launched in 1977, is the farthest man-made object from Earth. It carries a record with sounds and pictures of Earth in case it meets alien life.
However, visiting stars is very difficult. The farthest humans have travelled is only about 400,000 kilometres. A trip to Mars takes six to nine months. Going to another star could take hundreds of thousands of years. Scientists have ideas like putting astronauts to sleep during the journey or building faster spacecraft. With international cooperation, this may become possible in the future. Humans have already landed on the moon, sent rovers to Mars, and photographed other galaxies.
