life on Venus

[Emperor Harkonnen]

I just read an interesting article about there being life on our neighbourplanet Venus. There was two astronauts who thought of the posibility of life in the atmosphere where it is no more than 70 degrees.

there is little water on Venus though, but they say that there might have been ocean covering the whole planet before the global warming of Venus.

This opens for new opportunities of where life can be present. but we will not know this untill 2005 when a sattelit is being sendt to Venus to see wheter there is life or not.

[nampigai]

it will surely set the whole thing in a new perspective. if there's life on our two neighbour planets, the scepticals will have something to grumble about cause surely it would be evidence enough that there MUST be life many otherplaces in this universe.

[Emperor Harkonnen]

yes, but it does mean that when life comes and creates a foothold then it will need more drastic changes in the climate to exterminate it.

[Emperor Harkonnen]

anyone else got any views on this?

[Davidu]

As I know, the atmosphere is composed mostly of sulfuric acid, it is too hot for anything to live there (but who knows?), and the pressure is also too big (again: who knows?).

If the temperature and pressure can be taken care of by nature, the sulfuric acid could mean problems...

[Emperor Harkonnen]

now this life lives of that acid. it is its energy, it's food. and it is not too hot, only 70 degrees as I said. that is not very hot, there are living things on earth who can stand more heat.

and what pressure are you talking about?

[slaphapy]

I'm not really sure about this 70 degree stuff... Venus has the highest surface temperature of all the planets. and it's atmosphere is made up mostly of CO2 and H2SO4 (sulfuric acid)... also Venus has no magnetosphere so it gets full blasts of the Solar Wind, making it much hotter... btw in the thread Global warming, people started talking about this as well.. ;)

I would highly doubt we find life on other planets before Earth no longer exists... especially on other planets in our solar system... Mars and Venus are probably the most likely.. but still not very probable, Venus is too hot, and Mars has no water (and polar icecaps made out of frozen CO2, not water). But Titan and IO i believe... but I could be wrong, are the most likely to be able to have life, but they are moons of Jupiter... but even then I doubt we will see any life develop on the moons before Earth no longer exists...

[exatreide]

Europa probebly has some form of life on it.

not to qoute movies but..

life alwas finds a way...

[slaphapy]

probably, but not any inteligent life.. it's probably just some kind of form of bacteria, or other single-celled organism.

[exatreide]

But still...

The church nazies can shove those single cell life forms up their pipes and smoke em.

hehehe.

Inteligent life in the solar system? most likely...

no...

Hehehehehe

[Miles]

probably, but not any inteligent life.. it's probably just some kind of form of bacteria, or other single-celled organism.

Probably, but a extra-terrestrial single-celled organism is more significant than you give it credit for.

[slaphapy]

i'm not saying it is insignificant... it takes millions of years for that to happen, but a bacteria can't think... it's not inteligent in any way... I just highly doubt that we, or anyone for that matter, will find life either in the universe or even in our solar system... i mean it takes, what? 8 months to get to mars on current technology? and Jupiter is a little more than twice the distance that mars is from us. we may find living bacteria, or even evidence of there being bacteria in our solar system some day, but I highly highly doubt it will be on Venus... we have bacteria on earth in the archeabacteria kingdom (i think that's the name) that live to as high of temperatures as the mouths of volcanoes... but not any hotter than that.

And venus is much hotter than the earth, all over the surface, so I doubt even something as simple of an organism such as a bacteria will live there, ever. Unless the sun shrinks (which won't happen)

[exatreide]

thats inposible.

as is men flying in the air.....

For Other interesting facts about the planet Venus

Go to this URL http://solarsystem.nasa.gov/features/planets/venus/venus.html

Here are some of the highlights from the page:

At first glance, if Earth had a twin, it would be Venus. The two planets are similar in size, mass, composition, and distance from the Sun. But there the similarities end.

the thick atmosphere allows the Sun's heat in but does not allow it to escape, resulting in surface temperatures over 450

[slaphapy]

what's impossible? the sun shrinking thing? ... well actually it will shrink in some way, but not after it grows and destroys the earth first ;)

ya I always thought the fact that it's day was longer than it's year was funny ;D

[Emperor Harkonnen]

On Europa there can live manets, like the once in the oceans of earth, no?

anyway, it is 70 degrees on the atmosphere of Venus that's for sure. and they believe that it was covered with oceans with one celled organisms, which after the global warming of Venus(the global warming is a fact) adapted living in the atmosphere because there is 400 degrees on the surface. Life needs much water to be created, but little water to go on living. These bacterias live on the acid, just like some of them on earth do, near the underwater vulcanos. they can stand very very hot climate. and I am fully aware of the rotation thing, it was also in that article.

so it is not impossible at all for life to exist on Venus!

if only mars had water and was a little hotter there would probably be life there. the tempratures on mars are -50 till 0, if I am correct.

[Emperor Harkonnen]

and that article is wrong about the water, there is water on Venus

[slaphapy]

i still do not know where this stuff about the atmosphere being 70 degrees is... that is incredibly not true, unless they are talking about the very top of the atmosphere, even then I bet it isn't 70 degrees

[TMA_1]

geesh...

I will just go with the evolutionary model for a second. Dont you guys see how rare life is? dont you guys know how hard it is for the right kind of amino acids to come together and for others to be created. It would take so many variables to solve this. we havent been able to duplicate a process to make DNA or RNA. so how could you say, "well, if that planet is hospitable enough, then of course its possible!" geesh.lol a lot of people like to bring up the fact that there is life deep under our oceans. That is totally true, but there was basic life on the earth in the first place. that life adapted to incredable change. Life cannot start out in such harsh places. if you say it can, then give me the evidance. if not, then say the truth that it is an assumption. just get annoyed that so many people think its just a given and take it for granted. why evolution is believed is beyond me. God made it all.lol

[Emperor Harkonnen]

yeah I know, life cannot begin in harsh places it has to begin in a perfect place, which there is a theory Venus was before. that it was just like earth covered with oceans and about the same temperature. but then the global warming started. maybe there was an intelligent creature who did that, and then fled the planet, no I am just kidding :)

but I am open for the possibility of life even on the coldest moons of Jupiter. I want it to be like that and therefore I would like to believe in it.

[number6]

anyway, it is 70 degrees on the atmosphere of Venus that's for sure.

Oh, you are talking about the upper atmopsphere. I would buy that, but since life can not exist at such high altittudes I don't see the point of mentioning that temperature.

[Emperor Harkonnen]

I don't know at what altitude, but it was on an altitude which life could exist. I think astronatuts know that a little better than you do

[number6]

Fair enough. Since you would not post a link to story backing up your information I was forced to go searching myself. I found this link:

http://www.newscientist.com/news/news.jsp?id=ns99992843

Even if microbes do live in the upper atmosphere of the planet, the planet itself is still uninhabitable. Mars is a better place for research as far as the search for life is concerned IMHO. Here is a quote from the article linked above:

"From an astrobiology point of view, Venus is not hopeless," says Dirk Schulze-Makuch from the University of Texas at El Paso.

The article points out the possibility of life, but it is not a forgone conclusion. While I agree that this is an interesting theory we will have to wait to see if the "astronauts"/scientists are right. Right now as far as anyone knows there is no life on Venus.

[Emperor Harkonnen]

and I mentioned before that I couldn't post a link because I read this in a magazine and not on the internett.

and thanks for finding something to back me up :)

I really hope that the satelitt they launch in 2005 will find life. it will study Venus at an altitude of about 60.000 or something

[number6]

While I would welcome the news too, I am a little skeptical even though the scientists in the article have some very good reasoning. It just does not seem possible on a planet like Venus. I believe we need to know more about all of the planets so I welcome any missions to Venus, but I am more interested in Mars myself because there are real possibilities of humans actually colonizing that planet.
