Titan is so frigid — about –290 degrees Fahrenheit [–179 degrees Celsius] — that the liquid present there is made up of hydrocarbons like methane and ethane.) But even such a large moon ...

These vast expanses of liquid, however, are not water but hydrocarbons such as methane and ethane, forming seas, lakes, and ...

The video shows actual footage from the spacecraft's point of view as it passed through the hazy layers of Titan's atmosphere, spotted "drainage canals" that suggest rivers of liquid methane run ...
