CONTEXT:

• Saturn’s largest moon Titan has small liquid lakes that run more than 100metres deep, perched atop hills and filled with methane.
• This was founded by scientists using data from NASA’s Cassini spacecraft.
• The findings are published in the journal Nature Astronomy.
• They provide new information about the way liquid methane rains on,evaporates from and seeps into Titan.

BACKGROUND

• The NASA probe found that Saturn’s largest moon has small, deep lakes filled with methane.
• Titan is the only known body in our solar system other than Earth with a liquid on its surface. But rather than a water cycle, it has a methane and ethane cycle.
