Mysterious guide vivid stripes accept been discovered on Saturn's Moon Dione, says question yesteryear Planetary Science Institute Associate Research Scientist Alex Patthoff.

"The prove preserved inwards the linear virgae has implications for the orbital development in addition to impact processes inside the Saturnian system," Patthoff said. "Plus, the interaction of Dione's surface in addition to exogenic fabric has implications for its habitability in addition to provides prove for the delivery of ingredients that may contribute the habitably of bounding main worlds inwards general."
Patthoff in addition to Emily S. Martin of the Center for public in addition to Planetary Studies at the National Air in addition to Space Museum, are co-authors on a novel newspaper "Mysterious linear features across Saturn's Moon Dione" that appears inwards the magazine Geophysical Research Letters. They studied images from NASA's Cassini spacecraft, which likewise revealed similar features on Saturn's Moon Rhea.
Dione's linear virgae are mostly long (10 to 100s of kilometers), narrow (less than v kilometers) in addition to brighter than the surrounding terrains. The stripes are parallel, seem to overlie other features in addition to are unaffected yesteryear topography, suggesting they are amid the youngest surfaces on Dione.
"Their orientation, parallel to the equator, in addition to linearity are dissimilar anything else we've seen inwards the solar system," Patthoff said. "If they are caused yesteryear an exogenic source, that could hold out around other agency to convey novel fabric to Dione. That fabric could accept implications for the biological potential of Dione's subsurface ocean."
