'Magic Islands' on Saturn's Moon Titan Explained

Scientists propose that the islands are chunks of porous, frozen organic solids floating on Titan's liquid methane and ethane lakes.

Scientists have proposed a potential explanation for the 'magic islands' on Saturn's moon Titan, which appear as bright spots on radar and can last from a few hours to several weeks.
The 'magic islands' are likely chunks of porous, frozen organic solids that float on the surface of Titan's liquid methane and ethane lakes.
The organic solids are formed from complex organic compounds in Titan's atmosphere that clump together, freeze, and fall onto the moon's surface.
The solids can float on the lakes if they are porous enough, similar to how pumice can float on water on Earth, before eventually sinking.
The researchers' model also suggests that a uniformly thin layer of these floating solids could explain the overall smoothness of Titan's lakes.
