Titan's Surface: Exploring the Frozen Surface of Saturn’s Moon
In Titan's Surface: Exploring the Frozen Surface of Saturn’s Moon, Professor Brian Cox describes how in 2004, the Huygens probe landed on Saturn’s moon Titan and revealed a surprisingly Earth-like surface. The probe observed flat, sandy ground with smooth, rounded stones — evidence that there was once flowing water on Titan's surface. This discovery has provided crucial insights into Titan’s geological history. This video is excerpted from BBC’s Wonders of the Solar System, a spellbinding documentary series that explores the most extreme locations on Earth to explain how the laws of physics carved natural wonders across the Solar System.

Q: What was surprising about the stones found on Titan’s surface?
A: The stones were smooth and rounded, much like river rocks on Earth that have been shaped by flowing water, suggesting that liquid water might have once flowed across Titan's surface.
Q: Why is the discovery of smooth stones on Titan significant?
A: The smooth, rounded stones indicate the presence of flowing water, which is significant because it provides evidence of liquid processes on Titan’s surface, similar to Earth’s geological history.
Q: How did the Huygens probe contribute to our understanding of Titan?
A: The Huygens probe sent back images and data revealing a thick, cloudy atmosphere and a surface with sandy ground and rounded stones, showing that Titan has some geological features similar to Earth.

Titan's Atmosphere: A Deep Dive Into Titan’s Mysterious SkiesIn Titan's Atmosphere: A Deep Dive Into Titan’s Mysterious Skies, Professor Brian Cox explains how Saturn’s moon Titan is unique in that it has an Earth-like atmosphere. Its deep, dense atmosphere is rich in nitrogen and contains methane. Though Titan is small, and therefore has weak gravitational pull, it is able to hold onto its atmosphere because the gases are very cold. This video is excerpted from BBC’s Wonders of the Solar System, a spellbinding documentary series that explores the most extreme locations on Earth to explain how the laws of physics carved natural wonders across the Solar System.
