The Phosphine Bombshell

In September 2020, a team of astronomers announced they had detected a gas in Venus's atmosphere that, according to every known chemistry, had no business being there. The announcement triggered one of the most intense and public scientific debates in recent memory, with rival teams dismantling the data, challenging the statistics, and proposing alternative explanations within months of the original publication. This episode takes you inside the full arc of that controversy: the 2017 telescope observation that started it all, the confirmation attempt, the firestorm of criticism, and the methodical, paper-by-paper response from the team that made the claim. The phosphine question on Venus is not yet resolved. But the fight over it has already changed the course of planetary science.
