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.


The scientists found hydrogen sulphide and sulphur dioxide - two gases which react with each other, and are not seen in the same place unless something is producing them.





The researchers told the New Scientist that "bugs living in the Venusian clouds could be combining sulphur dioxide with carbon monoxide and possibly hydrogen sulphide or carbonyl sulphide in a metabolism similar to that of some early Earth bugs".

They also believe the temperatures of Venus was once much cooler and there could have been oceans on the planet.

"Life could have started there and retreated to stable niches once the runaway greenhouse effect began," Mr Schulze-Makuch says.



Venus Inferior Conjunctions and Biological Events:

"Of the morning star, the great star, it was said that when it first emerged and came forth, four times it vanished and disappeared quickly. And afterwards it burst forth completely, took its place in full light, became brilliant, and shone white. Like the moon's rays, so did it shine. An when it newly emerged, much fear came over them; all were frightened. Everywhere the outlets and openings [of houses] were closed up. It was said that perchance [the light] might bring a cause of sickness, something evil, when it came to emerge.
But sometimes it was regarded as benevolent."
(Ancient Mesoamerican recollections of Venus)
Sahagun, Bernardino de., The Florentine Codex,
General History of the Things of New Spain - Book 7,
Salt Lake City, Utah: University of Utah, 1952, p. 1



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


Expecting to find high levels of carbon monoxide created by sunlight and lightning, the researchers instead found hydrogen sulphide and sulphur dioxide, gases normally not found together unless something is producing them. They also found carbonyl sulphide, a gas so difficult to produce by inorganic chemistry that it is generally considered to be a marker for living organisms.

Schulze-Makuch said there may be unknown ways to produce hydrogen or carbonyl sulphide, but both need catalysts. On Earth, the most efficient catalysts are microbes.

He suggested the bugs could be using ultraviolet light from the sun as an energy source, which would explain the presence of strange dark patches on ultraviolet images of the planet.

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.


Yet, in 2002, at the European astrobiology conference in Graz, Austria, Dirk Schulze-Makuch and Louis Irwin, from the University of Texas at El Paso, suggested that high clouds in the Venusian atmosphere contain chemicals that hint at the presence of some kind of biological activity.3 Based on data from the Russian Venera space missions and also the Pioneer Venus and Magellan probes, Schulze-Makuch and Irwin pointed to oddities in the chemical composition of water droplets in the Venusian clouds which, they argue, could be explained by the presence of microbes. The researchers found hydrogen sulfide and sulfur dioxide – two gases that react with each other, and are not seen in the same place unless something is producing them. They also said that, despite solar radiation and lightning, the atmosphere contains hardly any carbon monoxide, suggesting that something is removing the gas. One possibility is that microbes living in the Venusian clouds could be combining sulfur dioxide with carbon monoxide and possibly hydrogen sulphide or carbonyl sulphide in a metabolism similar to that of some early terrestrial microorganisms. Given that the temperature on Venus was once much cooler, there may once have been oceans on the planet. Life could have started there and retreated to stable niches once the runaway greenhouse effect began. This idea seems all the more reasonable following the discovery by Austrian scientists, also in 2002, bacteria living and reproducing within clouds on Earth. The Venusian clouds are high in the atmosphere, where the temperature and pressure are quite Earth-like.

Another problem could be UV radiation from the Sun. But Schulze-Makuch suggests that Venusian bacteria could make use of a natural chemical sunscreen there based on sulfur compounds. It's possible that organisms have evolved ways of making use of the UV, much like Earth plants use visible light for photosynthesis.


What about abiotic way?

What if reduced organic compaunds were brought to the Earth?

Did cells first form in an environment where monomers were abundant and then gradually evolve a photosynthetic capacity, or was photoreduction of CO2 and N2 a prerequisite for the first self-replicating entity? It seems likely that the Western Australian stromatolites were formed by photosynthetic organisms, but to what use was the light energy put? These questions require careful study, including detailed comparative analysis of contemporary metabolic pathways.

Sulfide may have been abundant on the early Earth, yet it has received little experimental attention with regard to its possible involvement in prebiotic syntheses. Hydrothermal vents and hot springs are rich in sulfide and have been suggested as sites of prebiotic synthesis. Thiol esters are more reactive than oxygen esters in many reactions and are important in contemporary biochemistry.



gaseous mixtures, for example, methane, nitrogen, ammonia, and water, if supplied with energy such as spark discharges, produce the amino acids including those found regularly in proteins. The distribution of monomers so produced is qualitatively and quantitatively similar to that found in carbonaceous meteorites. In addition, most protein amino acids may be produced nonenzymatically starting with simple organic compounds such as formaldehyde and hydroxylamine.


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:





This false-color view of the volcano Sif Mons was generated from Magellan SAR data and existing altimetry data. The image shows a region of the volcano just below the summit of the peak. A series of bright and dark lava flows is visible in the foreground. The brightest flows, which are relatively rough, are associated with the most recent volcanism in the region. The flows overlay older lava flows which are smoother and hence appear darker to the Magellan radar system. The volcano is 2 km (1.2 mi) high and 200 km (120 mi) in diameter. Vertical exaggeration in this image is about 20 times.



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.


The rising material pushes the surface of the planet upward, producing elevated topography. This uplift also stretches the crust, forming the observed rifts. The hot material may melt as it approaches the surface, producing the observed volcanos.

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."

"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:


When NASA scientists examined the camera they found that the polyurethane foam insulation covering its circuit boards contained 50 to 100 viable specimens of Streptococcus mitis, a harmless bacterium commonly found in the human nose, mouth, and throat. Since the camera had been returned under strict sterile conditions, it is evident that the microbes must have been on the probe since it departed the Earth and had survived 31 months in the absence of air or water while being subjected to huge monthly temperature variations and bombardment by hard ultraviolet radiation from the Sun. Conrad later commented: "I always thought the most significant thing that we ever found on the whole ... Moon was that little bacteria who came back and living and nobody ever said [expletive] about it."



There is also found bacteria on MIR Station.
source



Or 30 mil years old germ - 'sleeping':


here were much older spores waiting to be revived. On May 19, 1995, The New York Times carried a front-page story about them (4). Biologists Raul Cano and Monica Borucki had extracted bacterial spores from bees preserved in amber in Costa Rica. Amber is tree-sap that hardens and persists as a fossil. This amber had entrapped some bees and then hardened between 25 and 40 million years ago. Bacteria living in the bees' digestive tracts had recognized a problem and turned themselves into spores. When placed in a suitable culture, the spores came right back to life. As a control, the two biologists also attempted to culture from the same amber a number of samples that contained no bee parts. These cultures were negative, adding credibility to the experiment. This finding was originally reported in the journal Science (5) to general acceptance.


"... 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."


There are bacteria that metabolize iron, nitrogen, sulphur, and other inorganic materials. There are bacteria today that can live without sunlight. Archaebacteria that can withstand extreme heat have been found thriving in oil reservoirs a mile underground (9). Some species of cyanobacteria are highly resistant to ultraviolet radiation. The only thing absolutely essential for bacteria to live, grow, and multiply is liquid water. We are confident that the early Earth had plenty of water. Scientists believe that concentration of water in the earliest atmosphere for which they have data, over four billion years ago, was far higher than it is today.

Bacteria have the ability to colonize an unfriendly planet like the Hadean Earth. Not just had the ability but have the ability. These are not make believe stories. All of the bacteria we have considered, with all of their unusual abilities to survive extreme environments, are alive today!


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.

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





Source


Even though Venus has no appreciable magnetic field, the solar wind is prevented from reaching the surface by Venus's dense atmosphere and by electrical currents induced in its conducting ionosphere. The planet has a well-developed bow shock, but it does not have belts of trapped particles. Both the ionosphere and the extended corona of hot gas, derived from the upper atmosphere, help to divert the solar wind.

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!

Electric Universe theorist about “plasma“ tail:





The Tail of Venus

In mid-1997, the Soho satellite detected a plasma structure issuing from Venus and almost reaching the surface of Earth. The report described the structure as "stringy." Such a structure could only remain intact if a current were continuously flowing from Venus to the surrounding space via the plasma tail. The discovery supports the idea that Venus assumed its present position in the solar system only recently, and has not yet achieved charge-equilibrium with its environment.

Interestingly, ancient names of Venus include the Long Haired Star and Bearded Star. Symbols and glyphs that carried the meaning "planet Venus" also carried the meaning "comet."

We suggest that in ancient times, this same "plasma tail" of Venus emitted a visible glow by the same mechanism that comets do today, plasma discharge.

Ancient view of “ bright torch of haven“ ( (those days we are witnessing how Venus is glowing on night west sky...it is breathtaking)



The ancient Chinese Soochow Astronomical Chart says "Venus was visible in full
daylight and, while moving across the sky, rivaled the sun in brightness".
The Hebrews wrote "The brilliant light of Venus blazes from one end of the
cosmos to the other end." The Chaldeans described Venus as a "bright torch of
heaven", a "diamond that illuminates like the sun", "A stupendous prodigy in
the sky" that "fills the entire heaven.", and compared its light to that of
the rising sun. At present the light of Venus is
