___

I doubt that we would be able to fly there with our current spaceships.

___

Oh, don’t you know that scientists have found some potentially habitable exoplanets outside
the solar system?

___

I’m not sure about it. Not in this century!

Yes, I have. Sometimes I dreamt of life outside the earth when I watched sciencefiction movies
and read articles or books about astronomy. But I think humans won’t be able to live on
another planet.

___

Why not?

existing technology, supposing that we find one.

which helps to reduce the time they travel in space.

___

What is the closest habitable planet to Earth then? How far is it?

In August 2016 astronomers announced the discovery of a rocky planet in the habitable zone
of Proxima Centauri, which is the closest star to our Solar System. The planet is located
approximately 4.2 light-years from Earth.

E. READING
I. Read the passage and decide whether the statements are TRUE (T) or FALSE (F).
The word alien is a popular word for an extraterrestrial life-form, or a being from another planet. No
one knows whether there is life elsewhere in the universe. But some scientists think that it is possible.
Whether life exists on other planets or not, the idea of aliens has excited people for years. Lots of
people enjoy science fiction stories about aliens - also called extraterrestrials. Some believe that
aliens actually have visited Earth. Many people have reported seeing unusual objects in the sky. Some

think that these UFOs are alien spaceships. The presence of aliens on Earth has never been proven,
however.


Most scientists believe that for another planet to have life on it, it must be similar to Earth in several
ways. It is likely to need an atmosphere and water. It also must orbit a star, like the Sun, at a good
distance. This star would provide the right amount of light and heat for life to exist.
Scientists have studied planets and moons in our Solar System to see if they can support life. Space
probes have searched for traces of bacteria or other tiny living things on Mars. Some scientists are
also looking for the possibility of life outside our Solar System. Using radio telescopes, they hope to
capture signals from intelligent aliens.
So far, no evidence of extraterrestrial life has been found. However, scientists have discovered
hundreds of planets that orbit distant stars. Some of these planets are an ideal distance from their
stars, and some are roughly the size of Earth. It may be possible that life has developed on one or
more of them.
1. ____ No one knows for sure that there is life on other planets, excluding scientists.
2. ____ There is actually no extraterrestrial life-form in the universe.
3. ____ Both “aliens” and “extraterrestrials” refer to life existing on other planets.
4. ____ Many people have seen UFOs but they couldn’t prove that the UFOs are connected to aliens.
5. ____ To support life a planet needs to have an atmosphere and water and provides an amount of
light and heat.
6. ____ Only the telescopes are able to search for traces of living things in space.
7. ____ Scientists haven’t found any traces of extraterrestrial life on the moons in the Solar System.
8. ____ Scientists still can’t find any planets which are roughly the size of Earth.

Named after the Roman God of war, Mars is the fourth planet from the Sun in our Solar System.
Mars is also known as the ‘Red Planet’ because it’s red. This signature (1) ______________ comes

Everest.

Mars has two moons. One is called Phobos and the other Deimos.
A day on Mars is 24 hours and 37 minutes - only a little bit (7) ______________ than a day on our own
planet. A year on Mars, however, is almost twice as long, lasting 687 Earth days. This is because it
takes a lot longer than Earth to complete its (8) ______________ around the Sun.
Until recently, scientists believed that there was no liquid water on the (9) ______________ of Mars only rocks, soil dust and ice. In 2018, however, they found evidence of a lake under the planet’s south
polar ice cap.
Humans have not yet been to Mars, but scientists have sent (10) ______________ there to help them
research this fascinating planet. The first spacecraft to land on Mars was the Viking Landers, which
