These Ice Volcanoes Are Feeding Saturn’s Rings Which Marks A Good News In The Search For Alien Life

What you see is a moon. If you look very closely, it is very noticeable to get a glimpse on that small splay of light at its top, looking like a circular fountain.

It turns out this moon, called Enceladus, is a snowball containing what may be a sea of liquid water, warmed by the squishes and stretches of Saturn and other moons that pass nearby. All that gravity pushing and pulling on this little ball squeezes the liquid inside so it shoots up through some fissures at the top.

Nobody knew these volcanoes or somewhat fountains were there until the Cassini spacecraft flew near enough to Enceladus to find them. 

According to NASA’s series of images, Saturn’s ice moon Enceladus has been slowly ‘eaten’ by the gas giant’s rings. Like seriously folks, the images show ghostly tendrils escaping the moon’s cryo-volcanoes and shooting off into space.

Like Jupiter’s Europa, if Enceladus is thought to harbor liquid, it could possibly has life-containing oceans beneath its icy surface.

Not only that, a network of cryo-volcanoes on its south pole are constantly pumping out tiny chunks of ice-water and simple organic molecules at a roaring 800 miles per hour. Scientists believe these volcanoes are dredging up ocean water from deep beneath the surface, making them a tantalizing target in the search for alien life.

The images below, which were captured by the Cassini spacecraft and published last week in the Astronomical Journal, show long, sinuous tendrils of ice dust originating from the moon’s south pole geysers and reaching into Saturn’s massive E-ring.

According to NASA:

This collage, consisting of two Cassini images of long, sinuous, tendril-like features from Saturn’s moon Enceladus and two corresponding computer simulations of the same, illustrates how well the structures, and the sizes of the particles composing them, can be modeled by tracing the trajectories of tiny, icy grains ejected from Enceladus’ south polar geysers.

The figures labeled “a” and “c” are computer-enhanced images of the tendril structures near Enceladus that were taken at high solar phase angle (174 and 170 degrees, respectively); figures “b” and “d” are synthetic (computer-generated) images produced by following the trajectories of tiny, icy particles ejected from the 36 most active geysers (representing the top 50 percent of the moon’s total geysering activity) found on the south polar terrain. The match between real and synthetic images is quite good and strongly supports the suggestion that tendrils are produced by the moon’s geysers.

The next step for the astronomers studying the ice moon will be to ascertain just how much mass is leaving Enceladus’s oceans and making its way into Saturn’s orbit. The oceans will probably be with us for millions of years to come, but still, I say we take this as a sign that we ought to hit up those geysers sooner rather than later.
