Alien planets: otherwordly joys.

Hello, today I am going to write about a new planet, Its name is "Gliese 581 g" and It is an interesting discovery for the astronomy.
Gliese is a rocky planet, Its locations is the constellation Libra, It is a faraway planet, for example We delay 200.000year to arrive.
Gliese is very interesting, because Its have qualities as the Earth, as for example the size, for this reazon is a beautiful discovery.
Astronomy and the scientific world have always been looking for life in another planet, for this Gliese is very important, beause Its open the opportunity to find Alien life.
The NASA, at the past, sent a lot of expeditios to explorer another planet, as for example the robotical missions to Marte, Júpiter, Saturno. The missions for another planet have the intention to find water, because the water is a elementary substance for the life.
Gliese a faraway planet, for this is necessary a good technology to travel across the space, in this case the speed is very important because Gliese is located to 20 light year of the Earth.
Today, Astronomy have the focus in explorer the atmosphere that contain oxygen and methane and the water.
I Think that is very important in this moment the discovery of Gliese becuase open the imagination to find life in another planet, or in another galaxies.
