Dies wurde vor 20 Jahren genommen und verblüffte mich immer. Die Wikipedia -Beschreibung sagt, dass es ist "Zeigen Sie Hügel und topografische Merkmale, die einer Küsten- und Entwässerungskanäle ähneln"Und zu meinen ungeübten Augen sieht es wirklich aus wie ein Methansee auf der Unterseite des Bildes, mit Wellen und allem.
Dies wurde jedoch während des Abstiegs von Huygens aufgenommen, und es ist bekannt, dass die Sonde auf trockenem Land gelandet ist.
Was gibt? Sieht dieses Bild wie eine Küste aus, ist aber nicht oder zeigt es einen Punkt weit weg vom Landeplatz?

„It shows the boundary between the lighter-colored uplifted terrain, marked with what appear to be drainage channels, and darker lower areas.“
It’s believed to be former/seasonal lake’s bottom or features formed via seasonal liquid flow.
Soil was resembling moisturised clay by its mechanical properties (but it’s not literally clay!).
Liquid hydrocarbons can’t exist in tropical/equatorial regions of Titan for a long time, they are evaporating quickly. That’s why all stable liquid bodies are located in proximity of the poles.
Huygens landed in near-equatorial latitude.
Was about to say it also looks foggy, then I just learned fog can be made up of various different elements as compared to the water vapor fog we see here on earth, and that the fog seen on Titan, and likely in this pic as well, consists of evaporated liquid methane. Sorry if you already knew this, I just learned it* ☺️
To me, that looks like a foggy coast line made of liquid methane.
Don’t know, but an amazing photo of an alien planet.
Shore looks like it doesn’t it?
(Please excuse the bad pun/dad joke, but that was the first thing that ran through my mind when I saw the pic 🤣)
Yes. Titan is covered in lakes of liquid methane.
Cassini Huygens is probably my favorite deep space mission of all time. Whenever I see pictures and data from the Huygens probe I get a desperate urge for wanting to explore these distant worlds
Here’s hoping the Dragonfly mission amounts to something. But the distance to Saturn is a little worrying. To explore these places, time flies in the eyes of human mortality. To see HD footage from Titan would be a dream come true
