Is there life on Mars, no Venus?

[Biffer]

Bowie may have been looking the wrong way.

Royal Astronomical Society press conference at 4pm UK time, murmurs about the topic being astrobiology news in relation to Venus.

In the sci fi movie, the Covid survivors would now have some sort of immunity to whatever's coming from Venus.

I know it is only just the beginning of the investigation and that there is a long way to go before declaring life on venus, but fuck me - that has to be one of the most exciting things I've heard for years.

Knowing there is life on other planets (and by implication that it is possibly everywhere in the universe) would be epoch defining.

A basic microbial lifeform that exists to only produce gas...but that's enough about our Prime Minister, now to read up about the discovery on Venus.

Some religions will retreat further into the gaps, some will re-interpret their texts and some will refuse to accept unless (and possibly even if) aliens land on the White House Lawn.

Surely it was the devil himself, creating fake news.

Haven’t watched or read anything.

What is the evidence based on?

Actual samples from a probe, or some kind of deduction based on XYZ.

Something to do with gas and Venus and thus aliens

The Bahai will be fine.

[Hellraiser]

Hate to burst the bubble but all this means, as pointed out already by several astrobiologists, is that phosphine levels probably aren't actually an accurate or reliable measure of biological activity.

Detection of phosphine in the atmosphere for which they can't come up with a plausible, non-biotic explanation.

Though the paper points out that they are not claiming it is life, they are just saying they can't explain it.

[Biffer]

Yeah, the researchers have been very clear to say that. They were very clear that they’ve ruled out all the known Geological and atmospheric mechanisms for its production. That probably means there’s a new mechanism. It’s similar to the carbon monoxide on Titan results a few years back.

[Fonz]

Ok, I'm not too knowledgeable on astronomy despite generally finding it pretty cool...but I've always wondered if Venus would have been hospitable to life at an earlier stage of the Sun's lifespan, before a hotter, larger sun and a gradual buildup of gases turned it into the inferno it is today.

And correspondingly, whether the planets are meant to "take turns" being the habitable one, millions (or billions) of years apart. I.e. we'll turn into a fireball, but then eventually down the line Mars will have gained the capacity to develop something.

Is this possible or am I talking complete nonsense?

[stemoc]

this is a much better watch, forget Venus, the big guys know of their existence and have known for decades

Venus was probably a lot cooler in the past and possibly even had surface water. It seems that a runaway greenhouse effect turned it into the planet it is now - not because the sun is larger or hotter.

There is nothing to suggest that the planets are taking turns at being habitable - that would imply a guiding influence. It is just the way the planets have developed.

[Plato’sCave]

Interesting yes, but this is not proof of life, it’s just an observation we can’t explain.

[Biffer]

Interesting yes, but this is not proof of life, it’s just an observation we can’t explain.

Not quite. It’s an observation which we can only currently explain through a biological process, but we believe this is unlikely to be the cause and that it’s more likely there is an unknown chemical or geological process that will account for it instead.

Yeah that’s about it.

Venus is the answer to any halfwits who say that a greenhouse effect is just hypothetical.

[stemoc]

all it tells us that maybe a million years ago, venus had life but its now all gone cause in that million years, it moved closer to the sun and all life on that planet is now very much gone.... maybe a small packet of microbes remain but thats about it..if anything its a warning for us too..earth is only 150m Km away from the sun, won't be long till we reach 4-6 million km closer and seal the same fate as venus

I'd avoid those pesky 5g masts if I were you....

[Macropal]

There are no and have never been any plate tectonics on Venus, also it is without a doubt the most volcanic selestial body in our solar system. I'd say the odds of a once habitable planet is very low. The conditions are just in no way comparable to Earth. Mind you, the topographic relief when inverted colours are added does resemble planet Earth to an extent. Non-existent oceans aside.

No. We (and Venus) are moving away from the sun. The main reason for Venus getting so much hotter is the greenhouse effect.

[A6D6E6]

Just a point to add about the temperature on Venus and its proximity to the sun - clearly being closer to the sun has an impact, but Venus is hotter than Mercury which is even closer (and has an odd tidal locking mechanism) so you have to look to other factors - namely the greenhouse effect.

[Plato’sCave]

A fair response. I won’t be putting the flags out for our bug-eyed neighbours yet. If we do find them it will be most interesting to see how they wipe their arses.

Until then, I’m agnostic

It also spins in the opposite direction to most other planets. Probably flipped over at some point.

Jupiter has this gas as well but the process is known as much higher pressures and temperatures exist there.

Yeah, they both do, but those processes won’t be happening on Venus.

Won't be long?

lol tbf, we humans would completely fuck the earth up in less than 100 years, forget a million years

Yes, was going to suggest The Planets series is well worth a watch for us that love it but know very little.
