Nowadays humans are still wondering what planets in outer space might support life.
Scientists say planets need to meet three main conditions to support life. Firstly, they must have liquid water, so their temperature must not be too high or too low. Secondly, the planets need to have the correct amount of air so that they can hold an atmosphere around. Finally, their size is also important. If a planet is too small, its gravity is not strong enough to hold an enough amount of air. If it is too big, its gravity will be so strong that it will hold too much air.
Scientists are using space telescopes to find habitable planets. According to them, Mars is one of the most promising planets for life in our solar system. It is a planet like Earth. Its days last for 24.5 hours and its seasons are similar to Earth's. Although scientists have not found actual water on Mars, there seems to be traces of it on the planet's surface. However, the climate on Mars is unsuitable for human life because it is too cold and Mars lacks oxygen to support human life.
| 1. liquid | a. suitable for people to live in |
| 2. grativy | b. marks, objects, or signs that show that somebody or something existed |
| 3. habitable | c. in the form of a substance that flows freely and is not a solid or a gas |
| 4. promising | d. the force that causes something to fall to the ground |
| 5. traces | e. showing signs of being good or successfull |
