The hard-as-rock exterior of Saturn’s moon, Titan may contain within it stuff that only dreams are made of. Scientists have studied it and found a lot of things that have made them gaze into outer space in wonderment. In the past it was thought that a mighty ocean lay beneath its crust. This stoked hopes of there being life on Titan, since where there is water there is life.
Scientists analyzed the Cassini Probe’s measurements of Titan’s gravity field. Usually the greater the mass, the more the gravitational pull lies on its surface. But the results were really flabbergasting. The regions of highest elevation had the weakest gravitational pull and vice versa.
In order to explain this unnatural scheme of things on Titan, the scientists had to review their previous models. Most of these mountainous regions must have deep roots which displace water underneath them. And since ice has less density than water, this anomaly appears in the Cassini Probe’s findings.
Titan therefore has the toughest possible exterior to keep the floating icebergs beneath it from coming up to the surface. It all points to a strange core that Titan possesses. Unlike the layered structure of Earth’s interior, Titan’s central area may have an amalgam of ice and rock in it. There is even talk of a certain variety of industrial grade plastic being present among the substances found on the surface. What is required for further exploration into the matter is a Titan Orbiter. That would lend scientists on earth access to the necessary data in order to solve this Titanic dilemma.
