Reaching fr the Stars
Since the beginning f human histry, peple have lked up at the stars and wndered what they were like. Many ancient cultures believed that these pints f light were frm gds, r ther mysterius wrlds. Hwever, as science and technlgy develped, we learnt the truth abut stars. They are real places like ur wn sun, and they are farther away than anyne imagined. This raises the questin: Can we visit the stars ne day?
lk up抬头向上看
The man-made bject which has travelled farthest frm Earth is Vyager 1. This spacecraft was launched in 1977. In case Vyager 1 is fund by alien life, a special recrd with sunds and pictures frm Earth is carried n bard. It shws wh we are and where we are frm. By 2025, Vyager 1 was ver 25 billin kilmetres frm Earth, but that is still a lng way frm Earth’s secnd-clsest star, Prxima Centauri. That star is 4.2 light years away — abut 40 trillin kilmetres!
The challenge f visiting the stars gets even bigger fr space flights with humans. The farthest that any human has travelled in space is nly abut 400,000 kilmetres, t the far side f the mn. Time is a big prblem. At present, even a jurney t the planet Mars will take arund six t nine mnths. What will the astrnauts eat and drink during this perid? And hw abut their health and safety? These prblems grw when we talk abut visiting anther star. It might take hundreds f thusands f years t get there!
Scientists, hwever, believe that visiting the stars is nt a cmpletely wild dream. One idea is t have the astrnauts sleep during their jurney, like sme animals d in winter. Anther is t develp much faster spacecraft. While this is nt pssible right nw, with natins and scientists cperating with ne anther, there is hpe that the necessary technlgy will be develped. Humans have phtgraphed ther galaxies, set ft n the mn, and even successfully landed rvers n Mars. It seems likely that ne day we will reach the stars.
