As the Earth has a moon, so other planets have one too. Now dust storms have been discovered on Saturn’s moon called Titan. This has raised the possibilities of alien life on Saturn.
Sebastien Rodriguez, an astronomer at the Université Paris Diderot, France, and the paper’s lead author, said in a statement, “Titan is a very active moon. We already know that about its geology and exotic hydrocarbon cycle. Now we can add another analogy with Earth and Mars: the active dust cycle, in which organic dust can be raised from large dune fields around Titan’s equator.”
Titan is similar to Earth in some ways. It is the only moon in the solar system that has a substantial atmosphere; it is also the only celestial body other than Earth where stable bodies of surface liquid is known to exist.
The dust storms represent building blocks for life. NASA have said that it is possible the storms are comprised of “organic molecules” due to the chemistry of the atmosphere. There is 98.4 percent nitrogen in Titan’s atmosphere and about 0.1-0.2 percent hydrogen.
Rodriguez went on to say, “We believe that the Huygens Probe, which landed on the surface of Titan in January 2005, raised a small amount of organic dust upon arrival due to its powerful aerodynamic wake. But what we spotted here with Cassini is at a much larger scale. The near-surface wind speeds required to raise such an amount of dust as we see in these dust storms would have to be very strong — about five times as strong as the average wind speeds estimated by the Huygens measurements near the surface and with climate models.”
