Hidden ocean on Saturn’s moon bolsters life theory

શનિ‘s moon Enceladus is home to an ocean of melted water beneath its surface, and could be a source for alien microbes, વૈજ્ઞાનિકો જણાવ્યું હતું.

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 કેસ્સીની અવકાશયાન, and are described in the journal Science.

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 Enceladussouth polar jets contains salty water and organic molecules, the basic chemical ingredients for life,” લિન્ડા Spilker જણાવ્યું હતું કે, Cassini project scientist at NASA.

Their discovery expanded our view of the ‘habitable zonewithin our solar system and in planetary systems of other stars,” તેમણે ઉમેર્યું.

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

The Cassini spacecraft detected the shape of Enceladusgravity field during three flybys from 2010 માટે 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 mission is led by NASA, with the cooperation of the Italian Space Agency and European Space Agency.

The 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.
