The Great Venus Phosphine Debate - feat. Prof Jane Greaves

Does Venus have phosphine or not? Debate rages into the scientific community! In just two months a slew of papers have been released tackling this topic and today we catch up on what's been happening and speak with the lead scientist of the original discoverer paper - Prof. Jane Greaves - to give you the latest developments.

You can now support our research program and the Cool Worlds Lab at Columbia University
