Oft gab es Erklärungen für Phänomene, die man dort beobachtet, oft auch nicht.
Das neueste Rätsel gibt uns Titan auf, indem er eine mysteriöse "neue Insel" zeigt:
vier mögliche Erklärungen gibt es dafür:During previous flybys, ‘Magic Island’ was not visible near Ligeia Mare’s coastline (left). Then, during Cassini’s July 20, 2013, flyby the feature appeared (right)
•Northern hemisphere winds may be kicking up and forming waves on Ligeia Mare. The radar imaging system might see the waves as a kind of “ghost” island.
•Gases may push out from the sea floor of Ligeia Mare, rising to the surface as bubbles.
•Sunken solids formed by a wintry freeze could become buoyant with the onset of the late Titan spring warmer temperatures.
•Ligeia Mare has suspended solids, which are neither sunken nor floating, but act like silt in a terrestrial delta.
