Strange flying objects were photographed at two sites in San Juan, Argentina .-
wake is detected ultraviolet light reveals the presence of a natural electrical circuit that connects the planet Saturn with Enceladus, one of its moons.
Tuesday, May 10, 2011
This connection, whose existence was already suspected for a long time ago but had not been seen so far indicates that there is a stream of electrically charged particles moving between Saturn and Enceladus, and interacting with the magnetic field lines the planet. The phenomenon makes it a cloud visible glow near the planet's north pole, through a mechanism similar to that generated auroras on Earth.
The discovery was made thanks to a new observation of the Cassini space probe mission to Saturn by NASA and ESA, the space agencies of the United States and Europe, respectively. The discovery is the work of a team of specialists from Europe and the United States, including Michele Dougherty of Imperial College of London, Abigail Rymer (Johns Hopkins University in the U.S.).
For years, astronomers have tried, unsuccessfully, to glimpse through space telescopes telltale sign of stelae discovered bright as now.

Now, the Cassini spacecraft, due to its proximity Saturn and its instruments of observation, has given astronomers opportunity to detect these faint signals revelatory. When they shine the most, its light in the ultraviolet range is much lower than Saturn's polar aurora, but comparable to the weaker terrestrial aurora is visible without using a telescope.
The newfound power trail is about 1,200 kilometers long by just under 400 in width, covering an area comparable to that of Sweden. ![[Img #2212]](http://noticiasdelaciencia.com/upload/img/periodico/img_2212.jpg "Foto: NASA/JPL/JHUAPL/University of Colorado/Central Arizona College/SSI")
Among Saturn's moons, Enceladus is the only one in which violent geological activity has been detected. The main feature of this activity are the geysers that spew water vapor and particles functional space. This flow of matter gives rise to a cloud of electrically charged plasma that shoot high energy electrons along magnetic field lines toward the north pole of Saturn, producing the aforementioned wake like a polar aurora.
