Scientists observing Saturn's moon, Dione, spotted very strange scratches on it and a new one A study determined how these scratches could be found there.
As the report Space scientists were able to badyze the data captured by NASA's previous Cbadini mission, which ended last year. On some of Cbadini's photographs, clear, thin bands are visible on Dione's surface, and they are very similar to those that were also found on Rhea, another moon of Saturn.
However, on Dione, these lines are strictly parallel and seem to be fresh and new. They were also detected only in the middle of the moon. According to the co-author of the new study, Alex Patthoff, a geologist at the Planetary Science Institute, the orientation of the lines is quite strange and very different from anything that has been seen before, as explained in a public statement made by PSI .
"Their orientation, parallel to the equator, and their linearity are nothing like what we saw in the solar system. If they are caused by an exogenous source, this could be another way to bring new material to Dione. This material could have implications for the biological potential of the Dione submarine ocean. "

It was further found that the streaks found on this moon of Saturn were not affected by the topography, which demonstrates their relatively young age.
"The linear virgins of Dione are generally long (10 to 100 kilometers), narrow (less than 5 kilometers) and lighter than the surrounding lands. The stripes are parallel, seem to cover other features and are unaffected by the topography, suggesting that they are among the most recent surfaces of Dione. "
To learn more about how these stripes might have touched Dione, Pathoff asked if the surface of the moon could behave the same way as the tectonic plates on Earth, with different parts making In another theory, there may have been rocks moving around Dione leaving tracks in their wake: comets, though the other moons of Saturn, Helene and Polydeuces,
As Patthoff further explains, "the evidence preserved in the linear virga has implications for orbital evolution and impact processes within the Saturnian system." Moreover, the interaction of Dione's surface and exogenous material has implications on its livability and provides evidence for the delivery of ingredients that can contribute to the livability of oceanic worlds. in general. "
The new study demonstrates that the strange lines found on Saturn's moon of Dione is probably caused by debris from outside sources such as the rings of Saturn, was published in . Letters of geophysical research .
