随着科学的进步,空间技术的发展,越来越多的科学家相信:地球不是宇宙孤儿,在地球之外茫茫的大空里,存在有智慧生物的星球。为此,天文学家在地球各个角落,架起天线林立的射电天文望远镜,象大海捞针一样搜索来自天外“宇宙人”发出的无线电讯号,同时又主动地发射宇宙飞船到遥远的空间进行考察。1977年8月,美国天文学家们发射的“航行者”号宇宙飞船,将飞过木星,转向土星,向太阳系的边缘飞去。科学家们选择音乐来作为地球人类向宇宙智慧生物联络的信息之一。
With the advancement of science and the development of space technology, more and more scientists believe that the Earth is not an orphaned child, and that there is a planet of intelligent creatures in the open air beyond Earth. To this end, astronomers set up radio antenna telescopes everywhere in the earth to search for the radio signals sent by the “cosmic man” from the sky like a haystack while actively launching the spacecraft to a remote place for investigation. In August 1977, the spacecraft “Voyager” launched by U.S. astronomers flew over Jupiter and turned to Saturn to fly to the edge of the solar system. Scientists choose music as one of the messages that Earth’s humanity liaises with the intelligent creatures of the universe.
