Venus 'biohazard' to Earth?

They say that Venus surface is something like living hell coz of extreme hot temperature ( 450 C ) , permanent volcanic activity , acidic surface and high pressure (90 atmosphere).

But what about atmosphere ( thick layer of carbon dioxide and sulfuric acid clouds) at an altitude of 50 km : the temperature is about 70C and pressure is Earth like - about 1 atmosphere.

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

Scientist report Alien Life

Venus Express found that fluorescence glowing of Venus is in fact result of oxygen is "is produced when oxygen atoms present in the atmosphere recombine into molecular oxygen (or ?O2?) emitting light. Where does the oxygen come from?




Life on Venus may be microbe clouds

Congratulations! You (or rather, your sources) have solved not only one of the great mysteries of epidemiology but an even greater one: the mystery of the origin of life itself.

So viruses come from Venus.

The simplest type of virus consists of a strand of RNA encased in a protein coat.

Nobody knows how life originated, but a lot of biologists think it began with RNA.

The question is how a molecule as complex as RNA could assemble itself, or survive unprotected in the oceans of the young Earth.

Now we know the truth.

It didn't.

It came from Venus.

Well done!

Scientist speculation, before numerous missions( in fact - THE most visited planet by space missions, from Russian Venera, Pioneer, Magellan, Venus Express) assumed that clouds over Venus was just dust.



What about abiotic way?

What if reduced organic compaunds were brought to the Earth?



Nobody here is speaking about 'origin of life' - just a possibility that Venus atmosphere harbor 'life' and that existing Venus _Viral connection - especially following planets inferior conjunction and viral outbreaks on Earth. //

" Historically, outbreaks of new strains of influenza and influenza related illnesses (SARS for example) have occurred shortly, on average 83 days, after Venus inferior conjunctions."


The lethal wave of influenza in 1918-19... was first detected on the same day in Boston and Bombay. Yet in spreading within the United States it took three weeks to go from Boston to New York. ### Fred Hoyle and Chandra Wickramasinghe]

The discovery suggests how the molecular building blocks necessary for the creation
of life could first form in INTERSTELLAR SPACE!!!
The astronomers detected the 8-atom sugar molecule glycolaldehyde in a gas-and-dust cloud called Sagittarius B2. Such clouds, often many light-years across, are the raw material from which new stars and planets are formed. The astronomers detected the same molecule in a warmer part of that cloud in 2000, but the new detection shows that the sugar exists at an extremely low temperature -- only 8 degrees above absolute zero, the temperature at which all molecular motion stops. The cold glycolaldehyde detections were surprisingly strong when compared to the original detections and indicate that a considerable quantity of this simple interstellar sugar exists at extremely low temperatures.

A great thread with a lot of good information, I can not remember the
last time I've seen a thread with this much detail before.


Imagine what it would mean if we found life on Venus, Mars and Europa,
life would be a truly universal thing.

All this shows is that there's a correlation to venusian cycles and diseases - which can EASILY be coincidence.

And you're wrong...Venus is not very volcanically active (Earth is more so).

According to Magellan Radar imagery, Venus has a very "new" Surface.
Geologically speaking.


This is the theory as I remember it:

The surface of the planet seems to be roughly the same age, almost everywhere you look. But lacking tektonic movement (probably due to the lack of water as the lubricant). Venus may go into a total planetary dormancy as far as volcanic activity is concerned. Then..When enough heat builds up under the surface. All hell breaks loose, literally. And the planet is resurfaced.

Thank you iori_komei!

I think that life is universal // " Prebiotic chemistry might began in interstellar clouds!" //although how it begins is unsolved mystery. Life on Earth and its origins, I think, is just one pathway among many possibilities of how life and were can emerge, from various chemical 'soups' in Universe. And that life could be totally different - than what we expect it to be.

So - we must look everywhere: in solid crust. in hydrosphere and atmosphere for chemical syntheses.

Don't know about that much 'coincidences' - looking at upper chart!?

Venus IS volcanically active:







www.lpi.usra.edu...

Sapas Mons is the volcano in the center of this radar image of Venus. Sapas reaches a peak height of 2 kilometers, with two calderas near its summit and volcanic flows that extend for hundreds of kilometers across the surrounding plains. Two more volcanos, Maat Mons and Ozza Mons, are visible on the horizon. Maat Mons is 8 kilometers high, one of the highest features on Venus.

It is a reason that Venus have this very elevated topography.

Or this famous pancake volcanos:




"Magellan's images show a wide variety of interesting and unique features including pancake volcanoes (left) which seem to be eruptions of very thick lava and coronae (right) which seem to be collapsed domes over large magma chambers."

Very informative thread bluebird Im always interested in hearing about the origins of life and life on other planets but one thing Im wondering is how does life survive traveling lightyears through space?

Thank you CelticFC!


"You could take E. coli and rapidly cool it to 10° K and leave it for 10 billion years and then put it back in glucose, and I suspect you would have 99 percent survival — Leslie Orgel" //// Leslie Orgel, [quoted in] Here Be Dragons, by David Koerner and Simon LeVay, Oxford University Press, 2000. p 32-33



Think about extermophiles on our Earth - which thrives in extreme conditions like in permafrost and Artic ice or boiling water or deep inside earth in rocks or capable of tolerating high levels of dissolved heavy metals or some resistant to ultraviolet radiation or nuclear radiation.

Astrobiology is very interested in studying such organisms.

Than we have Streptococcus mitis ( that live normally in our nose and throat) which survive 31 month in space.
Surveyor 3- case of extreme survivability of bacteria and bacterial spores:




There is also found bacteria on MIR Station.

Or 30 mil years old germ - 'sleeping':



"... could life on this planet be descended from alien spores? ...Panspermia, the view that the seed of life is diffused throughout the universe, has been favored by a minority of thinkers since the Greek Anaxagoras in the 5th century BC. He, Arrhenius and Fred Hoyle may yet have the laugh on us doubters."



a lot of links to panspermia subject

Prebiotic chemicals are detected in interstellar clouds - comets - meteorites.



Regarding Venus : there is no magnetic field on Venus, so she has a 'tail' ( like comet !?) so solar flame can easily push such spores to Earth - and condition in upper atmosphere are more favorable than some of conditions in case with Earth extermophiles.








[edit on 23-4-2007 by blue bird]

hey great thread great info im beginning to see that panspermia is becoming a more accepted theory and info like this will sure help a lot of people who dont know a lot about panspermia learn about this theory and the origins of life anyway great thread keep up the good work

I never heard of that before, very interesting topic. How come it's atmosphere isn't depleted?

Fascinating stuff bluebird! you get a WATS from me you do




Venus is special, it has an induced magnetic field, just like a comet!




Source

Thanks Dae...and great diagram!

Magnetic dynamo theory states that in order to have a magnetic field, planet should have a liquid (conducting) interior. Some suggest that Venus has a solid interior iron core (( but we have radar imaging done by Magellan - which shows “recent“ volcanic eruption and lava flowed)).

So, the reason for lack of magnetic field on Venus is due to fact that planet SPINS very SLOW (243 Earth days for one spin).

Lack of magnetic fields result in lack of magnetosphere or radiation belts, meaning that solar wind directly runs in to upper part of Venus atmosphere forming a bow shock ( the bow shock on planets with magnetosphere is occurring out at the edge of their magnetosphere).

Venus tail was first discovered in '70 ( Pioneer Venus Orbiter): tail of charged particles stretching some 70 000 km from the planet.

SOHO solar probe reveal that the TAIL EXTENDS ALMOST TO EARTH orbit-- cca 45 million km!

When proposing that new discovered Gliese 581c “Earth“ like planet, have THICK ATMOSPHERE, in order to sustain life, because of proximity to red dwarf - we have a “thick atm.“ model again in function....claiming possibility of life!?
