Researchers believe Enceladus created an “ice shock” roar-Scientific Exploration-cnBeta.COM



One of the most interesting moons orbiting a planet in our solar system is Enceladus, called Enceladus. Researchers believe tidal pressure can cause sustained ice shocks on Enceladus’ surface. Astronomers and researchers are particularly interested in Enceladus, as it is one of the few places in the solar system where extraterrestrial life can exist.

Developing understanding of seismic activity on the Moon helps reveal what lies beneath the ice crust, while providing clues about the possible habitability of the subterranean ocean. Enceladus is the sixth largest moon orbiting Saturn with a diameter of about 500 kilometers. Its surface is almost entirely covered by ice, and it is very cold as it is about ten times further from the sun than the earth.

For a long time, people have speculated that there may be a large ocean of liquid under the ice crust. Presumably, the satellite experienced massive tidal forces caused by Saturn and other larger moons orbiting the earth. According to this theory, the massive tidal force on Enceladus will heat the moon’s interior and crack its surface. Sometimes high jets of water vapor gushing out of cracks, these cracks are called tiger cracks.

In this study, the researchers used observations from the Antarctic ice shelf to infer that tides on Enceladus can cause small earthquakes in the ice in the lunar rupture zone, just as observed in Antarctica’s floating ice.

Researchers say they have ideas about how thick the ice on Saturn’s moons might be, but they have no direct observations. They believe that studying ice shocks is one way to learn more about ice thickness. The study pointed out that even at the peak of its pressure, an ice shock is not a large-scale sudden collapse, but rather a continuous explosion and rupture over a long period of time.
