It turns out that getting an atmosphere—and holding on to it—really comes down to how big and how close to the sun you are (or, for Titan, how close you are to a really big planet).

If there's life in the solar system beyond Earth, Saturn's largest moon, Titan, seems a logical place to find it. A new study says maybe, but in tiny amounts.

In the upper layer of Titan's atmosphere, visible here in blue light, methane molecules are being dissociated by sunlight and recombining into ethane and acetylene molecules. Further down ...

Cassini used synthetic aperture radar (SAR) to look through Titan's thick atmosphere during these close encounters and found channels and large flat areas that are consistent with large bodies of ...

NASA’s groundbreaking Dragonfly mission is one step closer to its 2028 launch after successfully passing its Critical Design Review (CDR), as reported in a recent NASA Science blog post. The mission ...

Ride along on the outside of Huygens as it parachutes through Titan's atmosphere at nearly 200 miles per hour. Sound is basically pressure waves that are moving through some medium. So the sound ...

While all the ingredients are there, the moon's composition likely prevents them from coming together in any meaningful way.

On its way down, Huygens collected valuable data on Titan's dense atmosphere, finding a host of photochemical reactions — light-driven chemical reactions that shape the moon's chemical ...
