Listen to the text Is there Life in Space?0:05
And do tasks B and C in your student's book.0:09
Is there Life in Space?0:15
On a clear night, you can see many stars in the sky.0:19
Some of them can be seen with a naked eye.0:24
To see others, you require special equipment.0:27
A modern telescope can give you the advantage of seeing stars that are millions of miles away.0:31
Scientists want to know what the stars are like.0:39
Are they balls of fire?0:44
Do they have rocks or sands like our moon?0:46
Besides, there is another question they cannot answer.0:51
Are there living things on any of the stars?0:56
And if there are, do they have intellect?1:00
This question has always bothered people.1:05
But it was not possible to find the answer before now.1:08
Now scientists know more about space than ever before.1:13
Because now they have a variety of machines helping them to look for the answer.1:19
Unfortunately, people can't go to the stars and satisfy their desire for knowledge.1:26
The stars are much too far away.1:33
In case a person flew to the nearest star in a spaceship, it would take him hundreds of years.1:37
So scientists are sending out radio signals and carefully recording all the information they get.1:45
The radio signals go through space at the speed of light.1:54
At that speed, it will take 25 years for radio signals to reach the nearest star.1:59
Scientists predict that living things in space must have machines to hear the signals.2:06
We will not get an answer to our signals for more than 50 years.2:14
But scientists are already listening.2:19
They think someone from space may be trying to send signals to us.2:22
And who knows, maybe in the near future we will see the so called extraterrestrial in flesh and blood.2:29
As the expression goes, Scientists also have sent large telescopes into space.2:38
The telescopes are looking out into space, supplying us with scientific information.2:46
And above all, they are looking for life in other worlds.2:52
The problem that can leave no one indifferent.2:57
