CASSINI SPACECRAFT DELIVERS BIGGEST REVELATION YET: A MOON OF SATURN IS HABITABLE

Newsweek TECH & SCIENCE BY

Today Earthlings came one very giant step closer to finding life elsewhere in our solar system. In the final months of its 20-year mission, the spacecraft Cassini delivered its most noteworthy revelation yet: the ocean of Enceladus, a moon of Saturn, is releasing hydrogen, an energy source for some microorganisms. In other words, that ocean is inhabitable. “Enceladus,” says Cornell University astrophysicist Jonathan Lunine, “is the place to go to look for life.” . . . Read Complete Report

The wobble, technically referred to as a libration, reveals that the crust of Enceladus is disconnected from its rocky interior. Source: NASA/JPL-CALTECH

SATURN’S MOON ENCELADUS HAS A GLOBAL OCEAN BENEATH ITS SURFACE

EXCERPTS

“Saturn has more than 50 known moons, according to NASA, but one in particular has captured the attention of scientists: Enceladus. That’s because the moon has a global ocean beneath its surface, making it a prominent candidate in the search for extraterrestrial life. . . . “

“Previous data had suggested the ocean could be confined to the moon’s south polar region. However, by studying the magnitude of the wobble—known as a libration—which the moon shows when it is orbiting Saturn, the team concluded that the liquid ocean likely covers the entire core of the moon.” . . .

Saturn’s “UFO Moons”

 

from The Daily Galaxy

Strange flying-saucer-shaped moons embedded in Saturn’s rings have baffled scientists studying images transmitted by the ESA’s Cassini Spacecraft. Research suggests that the oddly shaped moons, Pan and Atlas, are born largely from clumps of icy particles in the rings themselves, a discovery that could shed light on how Earth and other planets formed from the disk of matter that once surrounded our newborn sun.

Observations by NASA’s Cassini spacecraft revealed the moons Atlas and Pan, each roughly 12 miles (20 kilometers) from pole to pole, have massive ridges bulging from their equators some 3.7 to 6.5 miles (6 to 10.5 kilometers) high, giving them the classic Earthly UFO appearance.

At first glance, one could assume that fast rates of spin might have stretched Atlas and Pan out into such unusual shapes, just as tossing a disk of pizza dough flattens it out. But astronomers discovered that each takes about 14 hours to complete a rotation — not nearly fast enough to cause the flattened, disk-like shape. . . . Complete  Report
