Geophysics NASA suspected theft of volcanoes on Ceres – TVOY GOROD Pskov

other icy worlds of our Solar system, like Pluto, Europa, Triton, Charon, and Titan may also have on its surface a cryovolcano, however, Ceres is different from them in that on the surface of this planet krivulkin Ahuna Mons stands in “splendid isolation”.

the Ahuna Mons Volcano on Ceres.

the Sea Mons, whose height is about 4 km and rises above the surface of Ceres as a considerable finger. On the Ground, this has no effect on the volcanoes, as they consist of not less firm rocks, but on Ceres volcanoes contain ice, making it possible to relaxation. According to researchers, this process could erase all traces of past cryovolcanism from the surface of a miniature planet. Very long this isolation was a mystery to scientists, but now they are convinced that they know the answer: the fact is that other cryovolcanism has been destroyed. Litter and his colleagues suggested that there was another force — a process called viscous relaxation. This leads to the fact that over time mountain “spreads” in the surrounding surface. Millions of years ago on Ceres likely had an impressive amount of spewing ciomaga breaks. And it became the root cause of the alignment of volcanoes on Ceres. In Geophysical Research Letters wrote about the Akhun mountain, which was form ed about 200 million years ago. The study’s author, Michael Sori, said that solar heat played a role. At the base of the Sea Mons clearly visible dome-shaped swelling, which can be another cryovolcano, whose age is about 500 million years.
