Seeing Saturn's Moon Titan

The video explores the Saturn system, focusing on Titan, the only moon with an Earth-like atmosphere. Due to its thick clouds, Titan's surface is invisible, but NASA's Cassini spacecraft, from 1997 to 2017, used radio waves to study it. By analyzing the waves' reflections and refractions, scientists discovered Titan's Earth-like properties, including propylene, cyanide, dunes, seas, lakes, and underground oceans.
