Reaching for the stars since the beginning of human history, people have looked up at the stars and wondered what they were like. Many ancient cultures believe that these points of light were from gods or other mysterious worlds. However, as technology and science developed, we learned the truth about stars. They are real places like our own sun, and they are farther away than anyone imagined. This raises the question, can we visit the stars one day? The man made object, which has travelled farthest from earth, is voyage one. This spacecraft was launched in nineteen seventy seven. In case voyager one is found by alien life, a special record with sounds and pictures from earth is Carried on board. IT shows who we are and where we are from. By twenty twenty five, voyager one was over twenty five billion kilometers from earth, but that is still a long way from earth. Second closest star proxy, senti. That star is four point two light years away, about forty trillion kilometers. The chAllenge of visiting the stars gets even bigger for space flights with humans. The far is that any human has travelled in space is just over four hundred thousand kilometers to the far side of the moon. Time is a big problem. At present, even a journey to the planet mars will take around six to nine months. What will the astronauts eat and drink during this period? And how about their health and safety? These problems grow when we talk about visiting another star. IT might take hundreds of thousands of years to get there. Scientists, however, believe that visiting the stars is not a completely wild dream. One idea is to have the astronauts sleep during their journey, like some animals do in winter. Another is to develop much faster spacecraft. While this is not possible right now, with nations and scientists CoOperating with one another, there is hope that the necessary technology will be developed. Humans have photographed other galaxies, set foot on the moon and even successfully landed rovers on mars. IT seems likely that one day we will reach the stars.
