I'm pretty sure you all have found some pretty dense atmospheres, but did they sustain life, or is it sustained by the life?

Here is my entry: 2391 atm... What is it made of, sand?

Is yellow, it could be a very acid atmosphere, and with that density any kind of liveform would be copressed many and many times more than in our planet, as it was underwater, and I think life could exist in a planet like this, if the life can exist underwater why not here? xD
(for life i mean, bacteria)

There are known species of Piezophiles (pressure-loving extremophiles) that not only thrive in, but require pressures over a thousand atmospheres to survive.1 So it is not totally inconceivable for at least microbial life to exist on that planet. smile

A good example would be the Mariana Trench and it's pancake fishes. What amazes me the most, though, is that in this planet the water is bellow the atmosphere... it's almost worrying to think how painfull evolution is under such circunstances tongue

Sticking to terrestrials, I think Gliese 581 c is a pretty good contender at 5358 atm:



EDIT: Whoops, didn't realise only planets with life count. Never mind, then.

Here is my entry, until I find one with a higher atmospheric pressure.

It actually looks pretty similar to MeZombieBiscut's.

I found one that beats zombiebiscuits by far. 6500 atmospheres! surprised

I'd question whether life could even start under such pressures, at least life as we know it. Whatever life is down there is alien by its very definition.

I wouldn't be too surprised if life can evolve there to be honest. The highest pressure environment that we know of (and can get to) on earth is the bottom of the Pacific ocean under more than 1000 atm of pressure. And we find life in that extreme environment; life which seems to be extremely old and possibly originated there.

I did wonder if water would still stable in the liquid state at 288K and 6500atm, so I checked the phase diagram and sure enough it is, but just barely.

WHat I have found is by far not the highest atmo pressure, but it stille xceeds 800. Pretty high imo. Fun thing is that I found it in a globular cluster. It must be relatively ancient...

With this atmospheric pressure , why we are able to see the ground ?

The planet should be a ocean of cloud (not to say an oceania of liquid gaz )

This is just crazy 6688.2 Atmo. Pressure
Also has very high gravity. 3.6231
How can life exist under these conditions I mean animal life not just bacteria.
This system has 3 planets with life the other two are moons.

This is certainly not a record breaker for this category, but a worthy mention. Specially because, well, it's the definition of RARE.
The system is: RS 8403-114-9-67729840-627 B6.1

2 terras with life under high atmosphere pressure, the moon is not tidally locked and has rings. The atmospheric pressure of the moon is of 1211.6 and it's roughly 100Km smaller in diameter than it's parent body.


Now some eyecandy!





CHALLENGE: Can you spot the moon in the night sky of boringland?

Nvm I found an even more extreme planet this is just extreme. It has extreme mass eXtreme gravity and it even has a moon with a larger diameter than itself.
8288.2 Atmo. Pressure
Gravity: 3.6888
Place: RS 1190-98-8-14355784-25 5
