Venus is a rocky planet, it doesn't have hellish depths like a gas giant does. The researches have no credible explanation how those quantities of phosphine can be produced on a rocky planet.
- jvanderbot 6y agoVenus has extreme heat and pressure at its surface. The temperature is around 500C, and the pressure is nearly 100 Bar (about the pressure at 3000ft depth). That is indeed hellish, and this is indeed a good question.

- sedatk 6y agoThe locations this was observed was more Earthlike parts of Venus in terms of pressure and temperature according to the article.
- jvanderbot 6y agoA chemical formed in one place can be transported to other places, especially in a well-stirred environment like the Venusian atmosphere.
- saberdancer 6y agoDepends on your definition of hellish. I guess Venus could be called that but it is not comparable to the pressures and temperatures that are found inside gas giants. For example Jupiter is estimated at 24000 Celsius at the core with pressures of several million bar. This is vastly different than environment on Venus and that is why they have no credible abiotic explanation for phosphine generation on Venus. My point was that Venus is not comparable to a gas giant.
