What is it?

Enceladus is the sixth moon orbiting the planet Saturn out of 62 moons. Enceladus is a very small moon, in fact it can fit inside the borders of the U.S state Arizona! Enceladus is also the most promising moon for hosting life.

The Discovery

Enceladus was first discovered by William Herschel who was a British astronomer. The date of the discovery of Enceladus was August 28, 1789. It was not until the 20th century that that we discovered more information about the moon. Voyager 1 and 2 passed several times in the 1980's and took pictures of it, the little moon got NASA's attention. In 2004 Cassini ( A robot spacecraft sent to Saturn) brought more understanding of the moon and took more pictures.

Appearance

Enceladus is the smoothest out of the moons. It is also very shiney scientists theory of the moon being very smooth is that in the past the moon was slushy all around, the slush filled the craters froze and created a smooth icy surface. Enceladus is very bright as well, it reflects 99.9% of sun that hits the icy surface. Because of the smoothness of the surface scientists say that Enceladus is a near perfect sphere. Under the icy crust there is an ocean of water which is another theory the scientists have since there is a Geyser that squirts out from the south side of the moon. The inside of the moon is a rocky core. The image below gives a good example of the layers

Possible Life

NASA has confirmed that there are water vapor jets that are propelling into space from the planet. You know what they say water equals life! Scientists say that it is very likely that there is some sort of tiny microscopic organisms in the waterpool below the icy outer crust. Enceladus is named the most likely planetary body in the Solar system. Witch means it is most likely to harbor life. This is very exciting.
