Travelling through the cosmos

Space is big. The Voyager probe, launched in 1977 to explore Jupiter and Saturn, took 36 years to leave the Solar System. It is the furthest human object from us, and it is still in our neighbourhood. Even the radio waves we sent into space have barely reached a few hundred star systems, and they…
