Scientists have discovered geological activity on Saturn's moon Enceladus

For several years now, scientists have been using NASA's Cassini space probe to explore Saturn and its moon. Experts have developed a new map of Enceladus, one of the planet's satellites, on which geological activity was discovered. The infrared images obtained revealed that there is a large amount of fresh ice in the satellite's northern hemisphere.

In 2005, scientists discovered huge plumes, which included ice and steam, probably emerging from the ocean below their surface. Pictures taken by the Cassini probe have identified approximately 100 geysers, from which salty ice vapor is emitted. According to experts, this is due to tidal forces. Saturn's gravity is capable of stretching and contracting Enceladus, causing internal heating and geothermal activity, while disrupting the outer ice sheet.

With the help of a new spectral map, it was possible to find out that infrared signals indicate geological activity located at the south pole. For this reason, experts are confident that there is ice in the Northern Hemisphere. At the same time, they note that, most likely, the landscape surface changed in both hemispheres.
“Infrared light shows the youthful surface of the South Pole. And this is not surprising, since we knew about jets exploding ice material, ”said Gabriel Toby, representing the University of Nantes and co-author of the scientific project.
