Titan

Titan is the largest moon of Saturn and the second-largest moon in the solar system. It is unique for its thick atmosphere, which is primarily nitrogen, and for having lakes and rivers of liquid methane and ethane on its surface. Titan's surface features—including dunes, mountains, and potential cryovolcanoes—make it a fascinating subject for scientists studying icy bodies. The moon is of particular interest in astrobiology due to its Earth-like processes and the possibility of life existing in extreme conditions. NASA's Cassini mission provided extensive data about Titan, deepening our understanding of this remarkable moon.
