9:53Now PlayingIn this episode, Neil deGrasse Tyson, joined by Chuck Nice, interviews David Grinspoon about how science fiction—especially Star Trek—has portrayed aliens and planetary science compared to real astrobiology. They discuss how early space propaganda, including the work of Wernher von Braun, Walt Disney, and Chesley Bonestell, helped shape public imagination about space exploration, while scientific understanding of planets evolved dramatically—from assuming every planet hosted life to discovering harsh realities like Venus’s runaway greenhouse effect. The core discussion explores how our imagination about aliens and planets has changed as real science caught up with speculation.
