U.S. National Aeronautics and Space Administration (NASA) image capture pull one of Saturn's moons, Iapetus, the Cassini spacecraft. The image was actually taken in August 2013 but just released by NASA in December 2013. Its uniqueness, Iapetus looks like a symbol of Yin and Yang. "This face is part of Iapetus that facing Saturn," the NASA statement said, as quoted Space, on Tuesday, January 21, 2014.

"The northern part of Iapetus is on top and rotated 30 degrees to the right. Imagery taken on the basis of visible light with the narrow-angle camera on August 30, 2013," NASA said in a statement. Some scientists think that the two faces of Iapetus associated with a slow rotation so that the dark absorbs more heat, it takes more time to heat up. |

Iapetus was first discovered by Giovani Cassini in 1872. Saturn's moon has unique because it has some sort of structure in the equatorial mountains. Scientists say, first, there is a space object collision that threw most of Iapetus, forming a new moon orbiting. Debris from the collision and form a new moon orbiting Iapetus. However, Iapetus gravity pull back the material so as to form a sort of mountain structure.
Another hypothesis, first Iapetus spun much faster than the current structure so that it can be formed. Cassini was launched in 1997 and arrived at Saturn in 2004. This vehicle will continue to investigate Saturn and monthly until 2017. *** [EKA | FROM VARIOUS SOURCES | SPACE]
