英语听力:自然百科 已知的宇宙:外星生命 Alien_Contact-1(在线收听

 For thousands of years, we’ve wondered if we are alone in the cosmos. Life, is it a one-time event, or it’s something that's occurred lots of times throughout the universe.?

 
And at this very moment, new discoveries are bringing us closer to the answers.
 
We are right on the course of being able to say life exists somewhere else.
 
All of our searching is leading to one ultimate goal  -finding intelligent life somewhere in the vastness of universe.
 
If we can discover an advanced civilization, it would be clearly the greatest discovery of humanity, beating out fire.
 
Get ready because The Known Universe is about to take you on a hunt for life out there.
 
Over the next hour we will show you how the hunt for alien life has dramatically changed over the past few decades. The lessons we are learning at the bottom of our oceans and the Yellowstone’s ethane pits are giving us dramatic insight into how life came to be on our planet. And it is helping us understand and imagine how life might emerge on an alien world. We will take you on a journey to far away planets where amazing creatures may roam their lands,creatures that make the wildest science fiction movies look like reality shows.  And finally we will show you how new technologies are being used to search for, and possibly communicate with at best alien civilizations.
 
So is earth the only planet where life has emerged in this vast cosmos? Are we alone or are we part of something bigger, a web of life that stretches light years through the universe?
