Scientists are looking for the cause of the mysterious appearance of "magic island" on Saturn.

The mark of the "magic island" has recently mysteriously appeared in radar pictures recorded in the large lake area on Titan - Saturn's giant moon. Scientists have argued quite harshly about this mystery and said that it is most likely the result of waves, bubbles or floating solids.

This mysterious object was discovered after experts compared the new picture and image recorded by the Cassini spacecraft to explore the Ligeia Mare lake system - Titan's second largest lake area in 2004.

Experts said that before July 2013, the area was quite flat and there was absolutely no phenomenon at all, including waves. Later, the mysterious object, dubbed the "magic island" suddenly appeared.

Cosmic scientist Jason Hofgartner of Cornell University said: "This finding tells us that the liquid lake area of ​​Titan's northern hemisphere is not only standing and moving. I don't know exactly what made the "magic island" appear but we really want to learn about it. "

Titan is the second largest satellite in the Solar System, composed primarily of water and ice materials. Titan's atmosphere is primarily nitrogen. Titan's climate consists of methane and ethane clouds.

With liquid (both above and below ground) and a thick layer of nitrogen atmosphere, Titan is thought to be a primitive Earth but has a lower temperature. Researchers have suggested that it is possible that marine fluids beneath Titan act as a biological environment.

Astronomers believe that the mysterious appearance of "magic island" is due to seasonal changes on Titan . Some hypotheses were made that some people thought that the wind formed the wave and created the "mystery" that appeared in the radar image; bubbles formed by gases pushing up from the sea floor or causing a solid object to float on the water .

Mr. Hofgartner said: "It is possible that wind, rain, high tide . affects methane and ethane on the lake area in Titan. Through this discovery, we can learn to better understand the similarities. each other, the difference in geological processes formed in Titan and Earth ".

The findings are published in Nature Geoscience.
