Titan: Saturn’s Glow-In-The-Dark Moon
Titan just never ceases to amaze. Saturn’s largest moon, it’s wrapped in a complex, multi-layered nitrogen-and-methane atmosphere ten times thicker than Earth’s. It has seasons and weather, as evidenced by the occasional formation of large bright clouds and, more recently, an area of open-cell convection forming over its south pole. Titan even boasts the distinction of being the only other world in the Solar System besides Earth with large amounts of liquid existing on its surface in the form of exotic methane lakes and streams.
We can thank NASA’s Cassini spacecraft for these discoveries, in orbit around Saturn since 2004, and now there’s one more for the tireless explorer to add to its ever-growing list: Titan glows in the dark.
