For years, scientists said“No"or "We don't know." But today, this is changing. Stan and Alexandra Barnett are astronomers. They believe intelligent life exists somewhere in the universe.They also think we will soon contact these beings. Why do Stan and Barnett think intelligent life exists on other planets? The first reason is time. Scientists believe the universe is about 12 billion years old. This is too long, say Stan and Barnett,for only one planet in the entire universe to have intelligent life. The second reason is size—the universe is huge. Tools such as the Hubble Telescope "have shown that there are at least 100 billion.galaxies,"says Stan.And our galaxy, the Milky Way, has at least 100 billion stars. Some planets that circle these stars might be similar to Earth. Looking for Intelligent Life Until recently, it was difficult to search for signs of intelligent life in the universe.But now, powerful telescopes allow scientists to identify many more small planets—the size of Mars or Earth—in other solar systems. If these planets are similar to Earth, they might have intelligent life. Making Contact Have beings from space already visited Earth? Probably not, says Stan.The distance between planets is too great. Despite this, intelligent beings might eventually contact us using other methods such as radio signals.3 In fact, they could be trying to communicate with us now, but we may not have the right tools to receive their messages.But this is changing, says Stan. Within the next 20 years, we could make contact with other lifeforms in our universe. 【词义推测】 Match the two words with the same meaning. Astronomer A.信号 Contact B.距离 Intelligent
