Uh oh. Venusians.

Or do they prefer to be called Venerians? :coolspecs:

Astronomers may have found a signature of life on Venus
Space Daily
...

Now, in a surprising twist, scientists at MIT, Cardiff University, and elsewhere have observed what may be signs of life in the clouds of our other, even closer planetary neighbor, Venus. While they have not found direct evidence of living organisms there, if their observation is indeed associated with life, it must be some sort of "aerial" life-form in Venus' clouds - the only habitable portion of what is otherwise a scorched and inhospitable world. Their discovery and analysis is published in the journal Nature Astronomy.

Possible marker of life spotted on Venus
Science Daily
Summary:
Astronomers have discovered a rare molecule -- phosphine -- in the clouds of Venus. On Earth, this gas is only made industrially or by microbes that thrive in oxygen-free environments. Astronomers have speculated for decades that high clouds on Venus could offer a home for microbes -- floating free of the scorching surface but needing to tolerate very high acidity. The detection of phosphine could point to such extra-terrestrial 'aerial' life.

Isn't that a byproduct of orgone?
The flash of light you saw in the sky was not a UFO. Swamp gas from a weather balloon was trapped in a thermal pocket and reflected the light from Venus.

As if there weren't already plenty of evidences right here on Earth.

Sure. They named it for the goddess of love because it eats files.

Yeah that makes perfect sense.

They say its because phosphines were discovered in the atmosphere.

Phosphines are a sign of life on earth because 20% of our atmosphere is oxygen. All phosphines have long since been oxidized to phosphates. The only way to get phosphates back to phosphines us to reduce them, and the only reducing agents in nature are bacteria and plants.

Venus is very much NOT an oxygen based atmosphere. Most of the atmosphere is hydrogen sulfide. On earth, hydrogen sulfide quickly reacts with oxygen to make sulfuric acid, which rains back down on earth.

Without oxygen, it's not surprising at all to see phosphines on a planet with an atmosphere that's saturated with sulfide because sulfur and phosphorus naturally occur together. It's not a sign of life.

If there were no sulfide in the atmosphere and a lot of oxygen, only then would the presence of phosphines be a sign of life.

I seem to recall it does rain H2SO4 on Venus.

Also something about phosphines and anaerobes.

Not to be pedantic, but this is inexact:
Venus Fact Sheet

Atmospheric composition (near surface, by volume):
Major: 96.5% Carbon Dioxide (CO2), 3.5% Nitrogen (N2)
Minor (ppm): Sulfur Dioxide (SO2) - 150; Argon (Ar) - 70; Water (H2O) - 20;
Carbon Monoxide (CO) - 17; Helium (He) - 12; Neon (Ne) - 7

Obviously I meant besides carbon dioxide and nitrogen, it's mostly sulfur.........just like besides being correct, you're mostly an asshole. :P :P :De_Bunk:


Just kidding. Thanks for the fact checking. :wink:

Same counter argument. Why jump to the conclusion that it is "produced" rather than inherent? There is known volcanic activity on Venus that is continuously pumping sulfur into the atmosphere. Phosphine could easily be off gassing from that. There are meteors discovered all the time with unusual ratios of particular elements. Could have come from one of those. Hell, we don't even have a good plausible theory for where the water on earth came from. The least ridiculous idea is heavy bombardment from comets shortly after the earth cooled, but that would take a shit load of ice comets of just the right size. Too big or too small results in the water blasting back into space as vapor. And why did all these comets hit earth and not the moon or other planets.

I'll answer the guy's question. Much of what we know or think we know about planet formation is wrong or poorly understood.

Bruce may have been wrong about the composition of Venus's atmosphere, but I think his point about the lack of O2 still stands.

The logic they are using to say its presence (phosphine) might be a "sign of life" is flawed.
