Evaporation, condensation, precipitation on my mind. This is the (methane?!) cycle and it happens all the time! 🎶
These Webb images, supplemented with images from the Keck II telescope, provide evidence for cloud convection on Saturn’s moon Titan, the only other place in our solar system with weather like Earth!
On Titan, methane plays a similar role to water on Earth when it comes to weather. It evaporates from the surface and rises into the atmosphere, where it condenses to form methane clouds. Occasionally it falls as a chilly, oily rain onto a solid surface where water ice is hard as rocks.
Titan is of astrobiological interest due to its complex carbon-containing chemistry. Organic molecules form the basis of all life on Earth, and studying them on a world like Titan may help scientists understand the processes that led to the origin of life on Earth. Using Webb data, scientists detected the methyl radical CH3, which forms when methane is broken apart. Detecting this substance means that scientists can see chemistry in action on Titan for the first time, rather than just the starting ingredients and the end products providing an intriguing place for further study.
Video description:
0:00 Zooming in on an artist’s concept of Saturn with its hazy moon Titan.
0:07 Titan’s hazy atmosphere fades to reveal darker surface features.
0:12 Artist’s concept of Titan’s surface, with a body of liquid in the foreground, reflecting the short, steep rocky hills and steamy yellow atmosphere behind it.
0:16 Rain starts to fall.
0:21 A methane molecule (CH4) appears.
0:23 An ethane molecule (C2H6) appears below it.
0:26 Artist’s concept of the Webb telescope reflecting its image of Saturn in its primary mirror rotates into frame.
0:33 Webb’s image of Saturn fades into an artist’s concept, which pans away to show Titan as a tiny dot.
0:37 The tiny dot of Titan dissolves into Webb’s image of Titan, a hazy yellowish globe, with blurred darker surface features.
0:39 Two blue circles highlight lighter white features in Titan’s atmosphere.
0:43 The circles are labeled Cloud A and Cloud B.
0:48 A methyl radical molecule (CH3) rotates in front of a background of wet dunes.
0:53 Methane molecules float in front of a hazy background.
0:55 They’re broken apart. Two of the remaining pieces of methane combine to form a larger molecule.
1:00 The molecules become a raindrop, which joins other raindrops falling on an artist’s concept of Titan’s landscape.
1:02 Pushing across the rocky landscape, through the rain, over a wide body of liquid.
1:08 The liquid begins to evaporate, and the thick yellow atmosphere evaporates.
1:13 Saturn becomes visible rising over rocky mountains in the distance as the sky becomes clearer and bluer.
1:27 All the liquid on the landscape has evaporated, and Saturn is clearly visible against a starry blue sky.
