StarTalk Radio
Return to Venus with David Grinspoon

Okay.

StarTalk Radio
Return to Venus with David Grinspoon

Yeah, that's my main answer to that point that Chris makes.

StarTalk Radio

But, you know, there's other objections like all that acid, you know, could likely really rise in sulfuric acid.

StarTalk Radio
Return to Venus with David Grinspoon

No, I don't mean that kind of acid.

StarTalk Radio
Return to Venus with David Grinspoon

The kind that makes you hear voices.

StarTalk Radio

No, I mean all that sulfuric acid.

But, you know, the more we study life on Earth, the more we find that life thrives in these extreme environments we didn't anticipate.

StarTalk Radio
Return to Venus with David Grinspoon

And and people have been sort of playing around with that chemist, alternative chemistries of life that could possibly survive.

StarTalk Radio

So I think, you know, it's it's just an interesting unknown phenomenon.

StarTalk Radio
Return to Venus with David Grinspoon

And there have been some observations.

StarTalk Radio
Return to Venus with David Grinspoon

It's just this sort of byproduct of actually kind of decomposing life.

StarTalk Radio
Return to Venus with David Grinspoon

It's, you know, it's a hydrogen-rich molecule.

StarTalk Radio
Return to Venus with David Grinspoon

So it's what we call a reduced molecule, which is common in biological materials, but not common in an atmosphere like Venus that's full of more oxidized and acidic materials.

StarTalk Radio
Return to Venus with David Grinspoon

So

StarTalk Radio

It's not something you'd expect on Venus.
