We should not have ignored Venus. Its easier to get to than Mars and the top of the atmosphere has reasonable temperatures. Why would a certain type of life would not be possible under 400 C or acid sulfuric environments ?

It might be very different from what we have on Earth, but is there anything specific to Venus current environment that makes us believe it is not possible, with the exception it would be very, very, different from what we have on Earth ?

I find the Venus images more interesting than Mars. Even more surprising, 30 years ago the Russians were flying balloons for days on Venus atmosphere !

"Soviet Balloon Probes May Have Seen Rain on Venus"

https://www.wired.com/2013/04/vega-venus-rain/

"The two 3.5-m-diameter balloons floated for nearly two days in the Venusian atmosphere around 55 km above the surface. Unlike the hostile terrain below, the cloud layers at this height are a veritable wonderland. Temperature and pressure are comparable to Earth’s average and there is ample sunlight streaming in from above. If not for the sulfuric acid clouds and hurricane-force winds, the atmosphere of Venus would be a comfortable living space."

The Planetary Society has these with post processing for better quality:

Actually venus is probably not worth it. It's runaway green house gasses definitely prevent a habitable environment. I think all life needs a stability point. Doubt the clouds could provide that. I think it would relatively easy to terraform than Mars though. You just need to start some sort of global cooling by blocking out the sun.



Why do you put spaces before punctuation?


This is off-topic but I think I can help.

Some languages, like (European) French, put spaces before question marks[0] and exclamation marks[1] and people might be so used to doing it that they even do it when writing in a different language.

Indeed. Thanks _Microft :-) As you you might have guessed English is not my native language.


The answer was good, but just to clarify a touch more... The software inserts the space, not the French speaker. I teach in a university in France and repeatedly instructed students to stop typing that space until a few told me they literally can't unless they switch languages in Word.


The Grammaire Française recommends:

"Toujours un espace avant et après: le point-virgule, le point d'interrogation, le point d'exclamation et les deux points."

https://grammaire.reverso.net/les-espaces-et-la-ponctuation/

But for French Canadian variations the indication is just a "smaller" space.


If it had not been for these clues, I actually would not have noticed.


Interesting thanks, I've never seen that before.
