Die Erde wird auch der \u201eblaue Planet\u201c genannt, da sie als einziger Himmelsk\u00f6rper in unserem Sonnensystem zu einem gro\u00dfen Teil mit Wasser bedeckt ist. Allerdings gibt es ein paar Monde, unter deren Oberfl\u00e4chen Ozeane vermutet werden. Einer davon ist der gro\u00dfe Saturnmond Titan. Ein Hinweis auf versteckte Wassermassen unter seiner Kruste ist die Entdeckung starker Gezeiten.<\/p>\n<\/div>\n

Anyone who visits the coast will be familiar with tides – the rise and fall in sea level twice each day. Less obvious are the tides which cause our planet’s crust to rise and fall a few tens of centimetres. These tides are caused by the combined gravitational pull of the Moon and Sun on the Earth. Tides on Titan are created in a similar way. However, this time it is the pull of Saturn which causes the moon to change shape during its 16 day orbit of the planet.<\/p>\n

Titan’s shape-shifting has been detected by carefully tracking the path of the Cassini spacecraft when it flies close to the moon. Differences in the way that Titan tugged on Cassini showed that the moon\u2019s gravitational pull \u2013 and therefore its shape \u2013 had altered very slightly. At its furthest point, when Saturn’s pull is weaker, Titan is almost spherical, like a football. When the satellite is closest to Saturn, it is stretched so that it becomes more like a rugby ball.<\/p>\n

Durch die so entstehenden Gezeiten steigt und f\u00e4llt die Titanoberfl\u00e4che um mehr als zehn Meter. Diese Verformung ist aber viel ausgepr\u00e4gter, als man sie bei einem bis auf den Kern festen Himmelsk\u00f6rper erwarten d\u00fcrfte. Dies weist also auf einen Ozean hin, der unter der 50 Kilometer starken Eiskruste m\u00f6glicherweise bis in eine Tiefe von 250 Kilometer reicht.<\/p>","protected":false},"excerpt":{"rendered":"
