BOULDER, Colorado -- A special study group has advised NASA that Venus is far too hellish of a world for life to exist on or below the planet's surface. Furthermore, while the potential for life in the clouds of Venus can't be ruled out, the expert panel gauged this possibility as extremely low.
The assessment concluded that "no significant risks" exist in contaminating Venus with Earth organisms on any future landers or atmospheric probes, including balloons. Likewise, any surface materials shot back from Venus or whiffs of its atmosphere returned to Earth pose no significant risk to our planet in terms of "back contamination."

But if you want to believe it's a fabled Venusian Sand Shrimp, feel free.

Absolutely, and I expect [the discovery of life elsewhere] in my lifetime.
Here's a book foreword on that theme, that I wrote last year:

But I've already come to my own conclusions on this issue YEARS ago and no one is going to convince me one way or the other off of what I think/believe here.
So you came to a thread with Venus in the title, clicked it, didn't bother to read it, then spouted off your opinion (and in the process shouted over others), without any regard to those who have had the courtesy to read, think, then post their thought's on the matter.
Feel better now? K, thanks.
People, now that high and mighty has finished, I think we are safe to start discussing again.

Your OPINION that life can't or doesn't exist on Venus is completely useless in the face of the SCIENTIFIC FACT that a parachute lander (which is what Russia's Venus Landers were) could NEVER have landed on Venus if Venus is anywhere even CLOSE to what we are told Venus is.
A parachute can't work in 90 Bars of pressure. Parachutes collapse at air pressure even slightly higher than Earth's (learned in 5th grade science class in a 5 gallon aquarium), nevermind 90 TIMES the pressure.
And what parachute material could they have used in the late 70's that would survive a slow decent through a 900-1500 degree atmosphere?
The Russian landers (the fact that they landed) prove without a doubt that the facts we're told about Venus are all complete lies. Because if they'll lie about the atmospheric pressure and temperature, they're lying about everything to cover up what's there. What other motivation could there be to outright lie about such simple things?

A nicely written forward. And I'm delighted to hear of your optimism. Let's all hope
The data on Venus obtained by Mariner V and Venera 4 are interpreted as evidence of giant polar ice caps holding the water that must have come out of the volcanoes with the observed carbon dioxide, on the assumption that Earth and Venus are of similar composition and volcanic history. The measurements by Venera 4 of the equatorial surface temperature indicate that the microwave readings were high, so that the polar ice caps may be allowed to exist in the face of the 10-centimeter readings of polar temperature. Life seems to be distinctly possible at the edges of the ice sheets.
The 50-100 organisms survived launch, space vacuum, 3 years of radiation exposure, deep-freeze at an average temperature of only 20 degrees above absolute zero, and no nutrient, water or energy source.
"John Lear Proven Right Yet Again."
Because that 900-1500 degree, 90 bars of pressure, sulfuric acid atmosphere version of Venus is complete non-sense sci-fi sillyness to keep us (the people) uninterested for who knows what reason.
Venus is almost the Earth’s twin in terms of its mass and radius. However, Venus has an atmosphere
very different from that of the Earth. With a surface pressure more than 90 times that of the Earth and
a composition of more than 95% carbon dioxide, an extreme greenhouse effect heats the surface of
the planet to temperatures of 730 K — hot enough to melt lead. The planet is completely enshrouded
with clouds, composed of concentrated sulfuric acid droplets that extend up to 70 km altitude.

The presence of substantial polar cooling of Venus, as derived from microwave interferometry at 10.6 cm wavelength, is shown to be open to doubt. Other microwave measurements give little evidence for significant pole-ward variation in temperature on the planet.
