1. What do we know with certainty?
We know that no life exists or ever did exists on the moon.
2.Why is there little chance that life exists on other planets in our solar system?
Because the conditions on them seem to be so bad.
3.Which planet may carry some sort of primitive life?
Mars may be the only planet that carries some sort of primitive life.
4.What do astronomers believe concerning the question "is there is intelligent life outside our solar system?
Some astronomers believe that as many as five per cent of all stars have life-carrying planets.
5. What do you get to know about civilizations in our milky way?
There is probably nothing so fascinating as the idea of entering into contact with such civilizations which perhaps do exist somewhere in space.
6. How could it be possible to receive signals from other civilizations?
Attempts are now being made by scientists to listen to stars by means of radio telescope in the hope of discovering intelligent signals,and some day the human race may indeed learn that it is not alone in he universe.

Ein paar kleine Zusatzkorrekturen habe ich noch:
| Terry hat Folgendes geschrieben: | 1. What do we know with certainty?
We know that no life exists or ever did exist on the moon.
2.Why is there little chance that life exists on other planets in our solar system?
Because the living conditions on them seem to be so bad.
3.Which planet may carry some sort of primitive life?
Mars may be the only planet that carries some sort of primitive life.
4.What do astronomers believe concerning the question "is there is intelligent life outside our solar system?
Some astronomers believe that as many as five per cent of all stars have life-carrying planets. (Der Satz klingt inhaltlich seltsam - Sterne haben Planeten?)
5. What do you get to know about civilizations in our milky way?
There is probably nothing so fascinating as the idea of getting in contact with such civilizations which perhaps do exist somewhere in space.
6. How could it be possible to receive signals from other civilizations?
Attempts are now being made by scientists to listen to stars by means of radio telescopes in the hope of discovering intelligent signals, and some day the human race may indeed learn that it is not alone in the universe. |
