Again Titan, amaze! Not only seas and lakes of methane on the surface but also an huge ocean of liquid water beneath! An extraordinary discovery from
Italian Scientist that cast new light and new questions on what we really know on our Solar System and on Extraterrestrial life.
There is an ocean of liquid water beneath the surface of Saturn's largest moon, Titan. The discovery, announced in Science, is due to an
international research team led by Luciano IESS, University La Sapienza of Rome. The study involved three other Italians Marco and Paolo Ducci
Racioppa, University La Sapienza, and Paul Tortora, University of Bologna. Titan never ceased to amaze when, in January 2005, the European probe
Huygens descended on its surface to Earth by sending extraordinary images of mountains and rivers of methane. To release the Huygens probe was
Cassini, the mission was born from a collaboration between NASA, the European Space Agency (Esa) and the Italian Space Agency (Asi). [...] The Cassini
data show instead that the deformation reaches a height of 10 meters, "a clear indication - underline the Asi and La Sapienza in a statement - that
Titan is not composed entirely of ice and rock-solid". For IESS "the discovery of such great magnitude of tides on Titan leads to the inescapable
conclusion that there must be a hidden ocean deep." The presence of the ocean helps explain why the atmosphere of Titan is so rich in methane (about
4%). "An ocean - explains IESS - can act as a reserve in depth, releasing methane dissolved in it, which migrates upward through the crust." But it is
above all an abundance of water to attract the attention of experts. "The search for water is an important goal in the exploration of the Solar
System. Now - IESS said - we can say we have located a place where it is abundant." The search for water is also important for the 'hunting' to alien
life forms, even though the researchers note, the most recent data suggest that life is more likely to develop in regions where liquid water is in
contact with the rock.
Titan's Underground Ocean June 28, 2012: Data from NASA's Cassini spacecraft have revealed Saturn's moon Titan likely harbors a layer of liquid
water under its ice shell. The finding appears in today's edition of the journal Science.
"Cassini's detection of large tides on Titan leads to the almost inescapable conclusion that there is a hidden ocean at depth," said Luciano Iess, the
paper's lead author and a Cassini team member at the Sapienza University of Rome, Italy. "The search for water is an important goal in solar system
exploration, and now we've spotted another place where it is abundant."
Step by step seems the old pillars and old certainties are being crumbled and perhaps a new scientific conscience will have to guide the next
investigations and future space missions.
Titan may hold Alien Life! Scientists say
