'Saturn's moon has signs of alien life': scientists

The first measurements of the subsurface water at the south pole of the small and icy moon were made by the US space agency's Cassini spacecraft, and are described in the journal Science.

The Cassini mission is led by Nasa, with the cooperation of the Italian Space Agency and European Space Agency. Italy supplies key telecoms, radar and measuring equipment to the mission.

The body of water is about the size of Lake Superior, the second largest lake on Earth, and has a rocky bottom which could create conditions that allow tiny life forms to thrive.

Researchers first raised the possibility of a below-ground ocean on Enceladus in 2005, after water vapor was detected spewing from vents near the moon's southern pole.

"Material from Enceladus' south polar jets contains salty water and organic molecules, the basic chemical ingredients for life," said Linda Spilker, Cassini project scientist at Nasa.

"Their discovery expanded our view of the 'habitable zone' within our solar system and in planetary systems of other stars," she added.

"This new validation that an ocean of water underlies the jets furthers understanding about this intriguing environment."

The Cassini spacecraft detected the shape of Enceladus' gravity field during three flybys from 2010 to 2012.

The gravitational tug exerted on the unmanned orbiter was carefully analyzed for clues about what the interior of Enceladus contained.

Researchers believe the 500-kilometer (310-mile) wide moon's ocean is encased beneath a thick crust of crystal ice.

"For the first time, we have used a geophysical method to determine the internal structure of Enceladus," said co-author David Stevenson, professor of planetary science at Caltech.

"This then provides one possible story to explain why water is gushing out of these fractures we see at the south pole."

The Cassini spacecraft was launched 2004 and has visited all of Saturn's largest moons.

The sixth planet from the Sun, Saturn is characterized by its unusual rings and has 53 known moons and nine provisional moons.

'Saturn's moon has signs of alien life': scientists

This would be nice, but the true is much less sensational. The new studies suggest an existence of the liquid layer of water that has a contact with the rocky core of the moon, and that's it. There is nothing that could be interpreted as a sign of life.

Existence of advanced UFOs 'beyond reasonable doubt', says Pentagon official who ran secret US government programme

The existence of unidentified flying objects using technology more advanced than human capabilities has been proved “beyond reasonable doubt”, the former head of a secret US government programme has said.

Luis Elizondo, who quit as head of the Advanced Threat Identification Programme (AATIP) two months ago, warned nations now “had to be conscious” of the potential threat posed by UFOs.

The unit, which the Department of Defense (DoD) insisted was terminated in 2012, produced documents that described sightings of aircraft travelling at extremely high speeds with no visible signs of propulsion.

Ben voilà, il n'est pas précisé à quelle(s) période(s) de l'année c'était !
Heureusement John en a identifié potentiellement un !
