NASA finds 'an alien Earth'

The latest data shows that Saturn's Titan moon has exactly the same terrain as Earth with mountains, rivers, sand dunes, lakes, valleys, craters . NASA calls it "Alien Earth".

The study has just published in the Astrobiology scientific journal of the US scientists group of many units, using data that Cassini research spacecraft.

Accordingly, Titan Titan is an icy planet covered by organic molecules, with many liquid methane lakes, which have Earth-like topography and excellent conditions to form life.

The only reason carbon-rich organic molecules have not yet evolved into life is probably because the moon is too cold (temperatures range from -179 degrees C to -300 degrees Celsius). This cold temperature also makes water on this planet exist only as permanent ice. However, scientists believe that warmer places - craters - should be the next target to search for alien life.

When the temperature is right, carbon-rich organic molecules can form amino acids, ie "life building blocks" as found in the ancient lake of Mars. These amino acids are prerequisites for making proteins, followed by life in the right sense.

Dr. Morgan Cable, from the Jet Engine Laboratory of the NASA System and Equipment Systems Deployment Unit, member of the team, explains that life will be created when organic molecules This primary is mixed into liquid water. Amino acids will be produced very quickly. This means that if we find a place warm enough on the icy moon to survive liquid water, that place may contain alien life.

Recently, NASA also published stunning images of Titan moon - their favored celestial bodies called "Alien Earth" , recorded in the latest approach. When the translucent gas layer surrounding the planet is removed, this beautiful moon exposes a fantasy surface with gentle tones such as earth orange, purple, light pink . under many shades of mixing and white of frost. .
