   Astronomers（天文学家）have spent hundreds of years searching for signs of life on other planets, using telescope. When they saw the geography of Mars, they thought they could see canals and that this might be evidence of intelligent life on the planet. More recently, however, spacecraft have been sent there to analyze the soil for signs of life. The results were negative and astronomers are now convinced that no life exists on the surface of any other planet in our solar system except Earth. To send a spacecraft far beyond our solar system is not realistic because of the huge distances involved.
   Unless life comes and visits us, the only was we are likely to know of its existence is from radio messages. Listening for intelligent extraterrestrial ( 天外来客)---or E.T. ---life is not a new idea, but the techniques now being used offer a much better chance of success than before. Looking for evidence（证据）of life in other solar systems now means using special radio receivers called radio telescopes to listen out for messages. The assumption is that intelligent forms of life would have discovered radio waves and would, like us, be using them to communicate. Through its research work, NASA (国家航空和宇宙航行局) has developed two means of systematically searching for E.T. life. The first method is to select the closest 800 stars like our sun and to direct a radio telescope to scan（细看）each one of them for electromagnetic（电磁）waves. The second way is to survey（眺望）the entire sky, listening for continuous signals which may come from extraterrestrial（地球外的）life. Scientists are looking in the 1000~10000 megahertz（兆赫）frequency range----a range where there are fewer natural radio signals which could interfere with transmissions（传输）. By looking for signals in these specific regions, scientists can avoid any confusion that might be caused by receiving a natural radio signal rather than one sent by intelligent life.
NASA’s search in space has already resulted in some discoveries----including sophisticated(尖端的) new communication and medical technologies.
