Signs of alien life detected on Venus
Signs of alien life detected on Venus

Molecules of Phosphine have been detected in the atmosphere of Venus. Until now, the only possible reason for the existence of Phosphine in such a location is as a result of microbial bacteria waste product.

This, if confirmed, either means we have potentially found alien life for the first time, or at the very least, a new scientific discovery regarding the production of phosphine.

Poor little sods have probably been trying to open a conversation with us for years by rhythmically opening their phosphine-flaps and blasting compressed sulphuric acid.

A sort alien 'yoo-hoo' that we've been completely ignoring for about 10,000 years. Only trying to let us know that the core of Venus is composed of a vast sea of naturally occurring Guinness.

Seriously though if as the article suggests it turns out to be emanating from microbial waste rather than a chemical accident then ET is back in business. Just one discovery confirmed of something like this and we'll have to have a fundamental re-boot on our perception of the Universe somewhat akin to the realisation that the earth wasn't the centre of the cosmos.

The atmosphere of Venus is mainly carbon dioxide and sulphuric acid droplets. The planet had a runaway Greenhouse Effect and the surface temperature is even hotter than the planet Mercury, with the nightside surface getting to ~400C on average.


Given that bacteria is found near undersea volcanoes on Earth, in theory bacterial life could exist there in the atmosphere. It would mean that basic forms of life may be commoner than was thought.

I think they tested a very hardy bacteria in space attached to the side of the ISS and found that it revived nicely having shut itself down and hibernated effectively.

Adds a bit to the panspermia theories too.

Probably turn out we've been attacked multiple times by really small space-bugs. And we shrugged it off as a species and just kept going. For all we know we could be the Truman Show of the Universe and Bexi and the girls on Fafargszat 19 are just settling into watch this episode.

A great chart that shows how weird Venus is temperature-wise.

The surface temperature of each planet can be roughly calculated from (1) it distance from the sun, (2) the sun's radiation output and (3) the planet's cross-sectional area ....

... every planet except Venus, which has such an awful atmospheric composition that it suffers from a runaway Greenhouse Effect.

GHE = GreenHouse Effect


Venus' carbon dioxide came from its volcanoes.

So, no, there are no Little Green Men on Venus. What is there (if anything) will probably only be visible in a microscope.

The implications behind it if confirmed there are living microbacterial organisms on Venus at any strata in the atmosphere are just immense though.

After watching some whining, maskless dick wail about his 'constitutional rights' as he tried to provoke a LIDL staffer to chuck him out of the store over the weekend, the western United States going up in flames, a 68% drop in Earth's species since 1970 and the RNC's Chairwoman Ronna McDaniel tweet that Biden was 'handling the Covid crisis badly' (WTF?) — I think Venus might just be a better option right now.

If it is Life then the implications are profound

- we are not Alone....

Of course the chances of their not being other life forms out there is very remote

- but finding another Planet like Earth near enough to actually study in detail is perhaps expecting too much.

The three planets - Venus, Earth & Mars could potentially all support life of the sort we have on Earth. They have solid surfaces, an atmosphere and are neither too close nor too far away from the Sun.

Mercury is too close to the Sun, too hot.
Jupiter, Saturn, Uranus & Neptune are gas giants with no surface.
Their Moons have surfaces and may support some form of life, though they are exceedingly cold..

Venus may once have been habitable, but volcanic carbon dioxide gave it a runaway greenhouse effect that blasted its temperature up hundreds of degrees to average of ~400C, it is swathed in clouds, the atmosphere pressure at the surface is intense (90 times that of earth, much like being 1000m under the sea), and is subject to massive lighting storms.

OTOH, Mars the Red Planet is a cold, dead place, with an atmosphere about 100 times thinner than Earth’s. It is the opposite of Venus in the thin atmosphere also means that heat cannot be retained at the surface. The average temperature on Mars is -81 degrees Fahrenheit (-63 degrees Celsius), with temperatures dropping as low as -195 degrees F (-126 degrees C). By contrast, the average temperature of Earth is ~57 degrees Fahrenheit (14C).

Earth is The Goldilocks Planet, just right for us. No surprise really, as we evolved in the stable climate, benign to complex life forms, the planet has had for the last million years. But, hey, we are doing our level best to change that!

If you are ever wondering about alien life forms, take a good look at The Irish, North and South, political class, there's a ton of absolute beauts there!:rolleyes:

I've always thought there was a lot in the theory that men are from Mars and women are from Venus. One of them even admitted it in a book. It would explain why there are two distinct forms of logic in the world. Male and female.
