Enceladus, one of the moons of Saturn, is a miracle like no other, with curves, geysers and a very ancient ocean under the icebreaker, but also hides mysteries that are not yet deciphered, says Dr. Robin Andrews, the Doctor in Experimental Volcanology, in his article published this week in the Forbes magazine.
So far, scientists have focused on the ocean of Saturn's sixth largest satellite, which may be a port some kind of life, and the seabed can not be very different from Earth. However, "there are so many that it can be understood about Enceladus, its inner ocean, its geysers that throw material into the universe, and even the engine that drives all this activity," says Associate Professor of Planetary Geology at North Carolina State University ( EE.), Paul Byrne, quoted by Andrews.
Try to decipher it Geological evolution and cryospheric features the Enceladus should analyze the grooves and cracks that extend over the surface of the satellite, and that's what makes a team of American researchers, of which Byrne is part.
The complex area of Enceladus
These cracks are morphologically similar to those formed when something damages the asphalt and the surface of Enceladus. that crack is spreading In a similar way, explained Molory Kinczyk, a research assistant in the planetary sciences at State University of North Carolina.
On the surface of that moon is complex and it will be influenced by many factors, among them perhaps the most important, extreme gravitational forces of Saturn and other satellites close to that planet. These forces, according to researchers, would generate heat in the canteen of Enceladus and would cause a kind of geological tide, which would explain the origins of the fundamental ocean movements and of the criluvulcanism in the southern pole of that moon.
Small moon with great geological activity
Enceladus has no tectonic weight on Earth, the only planet with which it is known active tectonic plates. However, this does not mean that tectonic plates are required to make a topography. For example, Mars, apparently without tectonic plates, has it the most famous volcano of the solar system: Mount Olympus.
For Kinczyk, it is strange that Enceladus is small compared to other much larger Saturn moons like Dion and Tethys, has great geological activity. On the contrary, Dion and Tethys show relatively small activity on their surface. Enceladus it's strange because we very little understand In this regard, the researcher points out.
At present, Byrne, Kinczyk and their colleagues have found that craters with a diameter of about 7 kilometers in diameter of the curved fibers have to do with the breaking cracks: those branch fissures or they become craters. It is very likely that the concentration of high-pressure craters corrects the directness of the cracks. However, much of the training mechanisms remain an enigma.
