Enceladus pulverizes its neighbors | category : satellites of planets | ||||||||||||||||||||||||||||||
The astronomers of the university of Virginia discovered that Enceladus In the Greek mythology, Enceladus is the eponymic Giant, overcome by Athena during Gigantomachy (the war of the gods against the Giants), buried under the island of Sicily and the person in charge of volcanic eruptions of Etna. The name " Enceladus " as well as those of seven satellites of Saturn known about the time was suggested by John Herschel, the son of the discoverer William Herschel, in a publication of 1847. , The sixth biggest moon of Saturn, pulverizes the surface of at least 11 other moons of Saturn of particles of ice. What explains that these bodies are among the most brilliant of the Solar system, Enceladus, is the most thoughtful body of our system with an albedo We call up albedo of a body, the report enters the quantity of light which it reflects or diffuses and the quantity of light which it receives. As comparison the albedo of the basalt is of 0,05 that of the lime is of 0,36 that of the chalk 0,85. The basalt reflects that 5 % of the successful light. The maximal reflectivity being 1. close to 1. " Enceladus modifies constantly the surface of the other worlds which revolve in the whirlwind of particles of ice that she generates ", asserts Anne Verbiscer, a scientist of the department of astronomy at the university of Virginia and a main author of the study appeared in Science on February 9th, 2007. " We nicknamed Enceladus ' artist in graffiti ' because of its capacity to modify the appearance of the other moons. |

The geysers of Enceladus | category : satellites of planets | ||||||||||||||||||||||||||||||
Enceladus has, in spite of its small size (500 kilometers in diameter) a geologic activity. | This one is supplied in every orbit of the moon around its planet.

Focus on Enceladus | category : satellites of planets | ||||||||||||||||||||||||||||||
| Ice moon of Saturn shows its full splendor. In the foreground, the bright white of Enceladus detaches immense shadows of Saturn's rings as seen in the background. This photo was taken on 28 June 2007, at a distance of approximately 291 000 km, by the Cassini spacecraft, using its camera angle during its mission 'Equinox'. This perfectly round white side of Enceladus, measuring 504 km in diameter. The objective of the Cassini spacecraft is on 15 October 1997, the date of its introduction, the study of the planet Saturn and several of its satellites, including Titan. The space probe Cassini-Huygens, consisting of the orbiter Cassini and Huygens module is in orbit around the planet and is about to complete his mission 11 years. | Huygens, which aimed to land on the moon Titan, was raised on Titan on 14 January 2005 returning to Earth, remote 1.2 billion km, information and spectacular images.

The large stripe of Enceladus | category : satellites of planets | ||||||||||||||||||||||||||||||
| The origin of this amazing scratch, several tens of kilometers on Enceladus is not explained, the Cassini spacecraft has been rescheduled in October 2008, by scientists to look more closely at the moon ice Saturn. What scientists are looking for is the possible presence of liquid water that may be under the frozen surface of Enceladus. Liquid water in extraterrestrial life, there is only one step in which the interest in great detail to explain this phenomenon. The dimensions of this stripe are impressive, both in depth, width and length. It could be due to a ground source heat kernel or back caused by a volcanic earthquake. |

Ice Fountains of Enceladus | category : satellites of planets | ||||||||||||||||||||||||||||||
| The surface of Enceladus, a moon of Saturn shows enormous eruptions of geysers of ice. A plume of ice have been photographed by the Cassini spacecraft during its flyby of Enceladus in November 2009. Deep canyons cut into the surface of Enceladus, where ice fountains rife. The plumes on top of that image, just gush on the limb of Enceladus. These fountains of ice were found on images from the Cassini spacecraft in 2005 and since then scientists have been observing them, hoping for clues on the possible presence of underground oceans, where life could develop. |
