Now researchers Clarification of tiger lines on Saturn’s moon Enceladus, The frozen little moon of Enceladus, Saturn, is a strange place. It is believed that the moon is only 300 miles wide and has an outer layer of ice that surrounds the ocean as deep as 20 miles that surrounds a rocky core.
At the South Pole of Enceladus four straight lines, parallel cracks or tiger stripes are cut off, from which water comes out. These cracks are not comparable to anything in the solar system.
We want to know why the eruption is unlike anywhere else in Enceladus in the South Pole, how this eruption can last for a long time, and why this eruption ultimately comes from cracks that are localized regularly, researchers say.
Saturn’s gravity exerts Enceladu’s tidal power, which warms and cools the small world. These forces are strongest at the poles. When liquid water under the outer ice sheet hardens into ice, it increases its volume and puts pressure on the ice until it breaks.
Enceladus’s surface temperature is minus 200 degrees Celsius. So, if cracks form in the ice, you will expect the ice to freeze quickly.
However, the south pole gap remains open and actually reaches the liquid ocean below.
This is because liquid water in cracks is deposited by the tidal forces produced by Saturn’s gravity and releasing energy as heat, the researchers said. This prevents freezing cracks.
Release of pressure from cracks prevents the formation of new cracks in other parts of the moon, such as the North Pole. At the same time, the water released from the cracks falls back like ice, builds up the edges of the cracks and weighs a little.
According to researchers, this caused the ice sheet to bend, enough to trigger parallel cracks at a distance of about 32 kilometers.
