Saturn’s Secret Oceans: Did Cassini Glimpse Life Before Its Fiery End?

Professor Luciano Iess, Planetary Scientist and NASA Exceptional Scientific Achievement Medalist

The Cassini spacecraft’s final moments were like a fading heartbeat—one last signal before silence. In this episode, Professor Luciano Iess takes us on a journey across the solar system, from Saturn’s icy moons to Venus’s runaway greenhouse effect. Hidden oceans beneath alien surfaces, the search for extraterrestrial life, and the delicate balance between planetary protection and bold exploration.

Quotable Insights:

🪐 "Cassini was called the moonlighting spacecraft. Wherever you looked, you found something new."
🌍 "To understand other worlds, you must first love your own."
🔬 "If an alien civilization observed Earth with our own technology, could they detect life? The answer may surprise you."
🌊 "We know there are oceans beyond Earth. The real question is: are they alive?"
