scientific community is intrigued by an object that appears and disappears at sea on Titan, the planet's largest moon Saturno.Los researchers, finding an explanation of this phenomenon, they named the object as an "island".
This "island" that comes and goes, was captured a year ago by the Cassini spacecraft of NASA in one of the seas of methane and ethane on Titan, an area that previously had been analyzed by Cassini, but had found no record subject to subsequent overflights.
A new study published in the journal Nature Geoscience, reveals four possible theories to explain this phenomenon on the moon Titan. All rule out the possibility that it is an "island" as they defined the object in the first instance.
The first says that waves could be more intense in certain Titan seasonal cycles that change every 30 years.
The second states that it is floating solids, indicating that might actually be composed of an iceberg frozen methane and ethane. The solids would sink, likewise, by the time the Moon is located.
The third option is that these structures could be covered with various organic compounds, which would make them able to float, but only on the surface of the sea. A phenomenon that would allow them to appear from time to time and not permanently.
And the last theory says they are gas bubbles, which would rise to the surface of the sea from the mouth of an underwater volcano that could appear as part of the mysterious island in Cassini images.
Now, scientists analyzed in more detail here on the largest moon of Saturn to discard or add more theories.
