A report published recently in the journal Nature has uncovered that the Cassini spacecraft of NASA has discovered the largest lake in the tropics of the Titan Moon of Saturn.

However, models suggest that lakes, which are standing bodies of liquid, may only exist at the at the moon’s poles. Also, a series of small lakes has been previously found on Titan’s poles by the visual and infrared mapping spectrometer.

And rain had also been seen evaporating in the equatorial regions. But, it is being said that it cannot reform lakes in the tropics.

Though, the recent findings have indicated dark areas known as Shangri-La, where the Huygens probe of the European Space Agency had landed in 2005, made its lamp’s heat to vaporize methane from the ground.

It is thus being said that the area is damp, which makes liquid methane in the equatorial region to evaporate. The methane then reaching the surface after being carried to the poles forms the polar lakes.

The team from the University of Arizona, Tucson, believes that understanding the formation of lakes in the tropical region of the Titan would be helpful for studying the moon's weather.

"An aquifer could explain one of the puzzling questions about the existence of methane, which is continually depleted", said Caitlin Griffith, lead author.
