As of November 2026, panspermia has been mentioned in one podcast episode on PBS Space Time (Oct 2025). Discussed as an alternative explanation for the presence of life on Mars.
Panspermia is the hypothesis that life exists throughout the universe, distributed by cosmic dust, meteoroids, asteroids, comets, and planetoids, as well as by spacecraft carrying unintended contamination by microorganisms, known as directed panspermia. The theory argues that life did not originate on Earth, but instead evolved somewhere else and seeded life as we know it.
