Because they lacked modern science to explain stars. Q1. What did some ancient cultures think about the stars? Why? Since the beginning of human history, people have looked up at the stars and wondered what they were like. Many ancient cultures believed that these points of light were from gods or other mysterious worlds. However, as science and technology developed, we learnt 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? Careful-reading Para1 1. Which is TRUE about Voyager 1? A. It was sent into space in 2025. B. It carries a special record with sounds and pictures from Earth. C. It has arrived at Proxima Centauri. D. It is the first manned spacecraft to the stars. Read para 2 to answer the question. 2. What is carried on board by Voyager 1? Why? A special record with Earth’s sounds and pictures. It is prepared in case alien life finds Voyager 1 and learns about humans. Careful-reading Para 2 The man-made object which has travelled farthest from Earth is Voyager 1. This spacecraft was launched in 1977. In case Voyager 1 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 2025, Voyager 1 was over 25 billion kilometres from Earth, but that is still a long way from Earth’s second-closest star, Proxima Centauri. That star is 4.2 light years away—about 40 trillion kilometres! Watch a video to know about Voyager 1 The challenge of visiting the stars gets even bigger for space flights with humans. The farthest that any human has travelled in space is only about 400,000 kilometres, 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! Careful-reading Para 3 Q4. What are the two ideas for travelling to stars? Q5. What space achievements have human beings made? Careful-reading Para 4 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.
