Is it possible that intelligent life was once on venus?

Question

They Say its our sister planet and before the greenhouse effect took a tole on the planet for the worse on....is it possible that intelligent life was on our sister planet .....would it be possible to tell by al the active volcanoes there that would destroy the evidence of life and the surface being 900 degrees so humans cant reach the ground to observe it

Answer 1

Well, spacecraft have landed and imaged the surface. I assure you, it looks rather dead.

What is your definition of "Intelligent Life"? I disagree with most people's definition, and do not believe there is a shread of intelligent life in this solar system... anywhere.

Answer 2

To my knowlege, the greenhouse effect never "took over" venus. It was there from the beginning. It is caused by the carbon dioxide that makes up most of the atmosphere on Venus, and by the fact that Venus' atmosphere is about 90 times as dense as ours. Both of these condition have probably existed on Venus since it first formed since planets tend to gradually lose, not gain atmosphere.

When "they" say that Venus is our "sister planet" all that means is that it's about the same size and mass. Just because Earth and Venus are similar in size doesn't mean there are any other similarities.

If the conditions on Venus have been the same throughout it's history then I seriously doubt any life as we know it could have ever arisen there. The kind of molecules that make up living organisms here would fall apart in the heat and there is no liquid water for them to be suspended in.

Answer 3

Venus is called Earth's "sister" planet because of its size and cloud cover. But the upper level clouds are made of sulfuric acid and the rest of the atmosphere is CO2. True, there was a time when Venus was different. But it's not clear it how Earth like it was or whether it was suitable for life. There may have been water, but there are no traces of water vapor in the atmosphere. Venus lacks a strong magnetic field to block solar radiation and solar wind, and we don't know if one existed anytime in the past.

So I would not think Venus ever had complex life forms, or any at all.

Answer 4

No, Venus is simply a vivid example of a 'worst case scenario' greenhouse effect. Environmental alarmists use it the way fundamentalist preachers use hell to scare people into their way of thinking. (interesting that Venus would really be like hell, except that a few more billion years before the sun burns out is a far cry from eternity)

I don't think Venus is a "see what technology does to planets?" example. If you'd like to see what the surface of Venus looks like, check this link: http://www.mentallandscape.com/V_DigitalImages.htm

The ground in these photographs is hot enough to melt lead!

Don't take my answer to think that I'm saying there is no such thing as global warming, or that we should waste resources, etc - just that some people go way too far in their alarmist predictions.

Answer 5

No. Not only are the temperatures on Venus too high but the acid atmosphere and the air pressure at 90 times the Earths would make it impossible for life to exist. If there was only one if these effects, life may be possible, but with all together it could not happen.

Answer 6

If intelligent life existed on Venus in the past, then they probably burned too much fossil fuels and made the planet a runaway greenhouse effect world. Maybe that's my guess.

Answer 7

Conjecture is that life doesn't exist there. That's because the environment is so deadly to life as we know it.

However, we know that life exists around underwater volcanoes... where there is no light, practically no oxygen except what is part of the chemical composition of the water, where temperatures would quickly cook life as we heretofore knew it.

If life exists anywhere but on Earth, it's highly likely we won't be able to recognize it.

Whether it is... or was... intelligent, as has been pointed out, there is reason to question the presence of intelligent life anywhere in the solar system.

Answer 8

Never. Venus was given its name by Roman astronomers, who named it after the goddess of beauty. However pretty, though, its atmosphere is full of carbon dioxide, a substance that would can any living creature should it breathe. Also, Venus's extreme temperatures can reach 900 F, so i really dont think anything could live on it.

Answer 9

No, we're pretty sure Venus was always a hellhole. It's just too close to the sun. It has no traces of past water as Mars does. Any clement period it had would have been much too short-lived for intelligent life to develop. It's been more-or-less the way it was now for most of its history.

Answer 10

No it is not possible because the temperature of Venus is too high from the time of its formation due its position(distance from the sun).
