Evidence of water on Mars. People used to think that Earth was the only planet in our universe on which life could exist.  But images taken by Nasa's Mars Global Surveyor in June 2000 using the Infrared Space Observatory's  spectrometers  raised  the prospect that indigenous life could exist on Mars. Some experts believe the source could be underground 'pools' of water.  This discovery is likely to spur future missions  and boost hopes for life  on Mars.

The discovery of water on  Mars. Some people have always thought  that there could be aliens on Mars. However, there was no proof. Their excitement has been rekindled  after ice  was found on the surface of Mars.  Water is vital for the survival of organisms.  The discovery of ice on Mars increases  the possibility of the existence of organisms on the Red Planet.  Gullies and reservoirs of underground water were found as well. Our dream to live on Mars could come true. Perhaps  one day we will meet each other somewhere on Mars, with a new outfit and a new house.

There are actually a lot more planets and stars in space. Besides the Milky Way Galaxy in which we live, there is the Triangulum Galaxy and the Andromeda Galaxy. Every time a new planet or a star is discovered, we learn a little bit more  about space. Although Earth is just a small, blue  planet, we can still discover things that are far away and we should be proud of  that. Also, we should realise  how insignificant we are. Discovering more about space is fantastic. It's like solving a mystery.

The moon lights up the night sky and  people have  expectations of that celestial body. The lunar terrain is  made up of a bleak desert  and inexhaustible outer-space dust. But the most interesting discovery  is that the moon is hollow. In addition, when a solid object suffers a hit, it may  cause two kinds of waves -  longitudinal  and surface.  But a hollow object can only measure the surface wave. The exciting thing is after the astronauts  landed on the moon and put the instrument on the lunar surface,  they found out that it did not record the longitudinal wave,  only the surface wave. Scientists were extremely surprised to discover that the moon is hollow.
