The Mysterious Event That Made Venus A Death Trap

The Mysterious Event That Made Venus A Death Trap


Sometimes we call the planet Venus “Earth’s
Twin”, but that’s only because the two planets are roughly equal in size. After that, not much else is similar and because
of the extreme temperatures on the so-called planet of love, humans would not stand any
chance of survival. In the words of one writer, Venus is a “hellish
world of infernal temperatures, a corrosive toxic atmosphere and crushing pressures at
the surface.” We just couldn’t go there. The temperature on Venus would melt anything
that got near it. But that might not have always been the case,
and as you will see today, perhaps in the past Venus might have been an altogether different
kind of beast. Let’s first give you a Venus 101. It’s the second planet from the Sun, behind
Mercury and in front of us. It was named after the Roman goddess Venus,
who among other things was the goddess of love. Sometimes you can see it without the aid of
a telescope, but only during a specific time in a specific place. There are a few things you need to know about
Venus and these relate to the reasons we just can’t go there even if we had the technology
to send people to the planet. One thing we doubt you know is that Venus
is the hottest planet in our solar system. The temperatures on the surface might be around
863 °F or 462 °C. It stays around that temperature never mind where you go on the planet. You can’t exactly get a respite from the
heat by taking a trip like you can on Earth. You might now be thinking how come Venus is
hotter than Mercury when Mercury is closer to the sun. The simple answer is Mercury has a very thin
atmosphere and Venus has a very thick atmosphere consisting mostly of carbon dioxide. The atmospheric pressure on this planet is
92 times stronger than that on Earth, so it would be like being 3,000 feet (900 meters)
underwater. In the words of NASA, if you somehow weren’t
melted on the surface of Venus you would be crushed. It’s this thick atmosphere that traps the
heat in, whereas Mercury lets the heat out into space. The heat dissipates on Mercury whereas in
Venus the thick atmosphere prevents this. Kind of like when you close the door to the
bathroom and take a really hot shower! You might be wondering how we got lucky here
on Earth and got this nice atmosphere, and some scientists have called this the Goldilocks
phenomenon. She got the right porridge, and it seems Earth
was perfectly situated at a distance from the Sun that we got the right atmosphere for
life to happen. We just got fortunate, but as you’ll see,
Venus might not always have been such an extreme place in the past. What does Venus look like on the surface you
might ask? Well, it’s rocky like Earth, but very barren. There are also lots of volcanoes there, although
much of the surface is made up of plains. There are some highland areas, and the highest
mountain on Venus is called Maxwell Montes, named after a Scottish scientist. The mountain is 36,000 feet high, or about
11 km. Just for a comparison, Everest is only 8.8
km high. So, we’ve got this extremely hot place that
can crush us. NASA also said the surface would stink like
rotten eggs, so that’s another reason to cancel your trip there. But perhaps it wasn’t always like that. You see, Venus is 4.5 billion years old. It’s mind boggling to think about just how
long that is because even a few thousand years is difficult to get into our heads. Suffice to say, it’s a lot of time for changes
to take place, and now some scientists are saying Venus in the past might have actually
been a bit more hospitable. New research that was talked about in 2019,
states that for around three billion years Venus might have had a climate that could
sustain water on the surface of the planet. That the temperatures could have not been
that high at all, with those scientists saying Venus might have had temperatures only around
122 degrees Fahrenheit (50 degrees Celsius) or as low as 68 degrees Fahrenheit (20 degrees
Celsius). But then there was climate change, according
to these scientists, and things got hellish. This change they believe could have happened
around 700 and 750 million years ago. But what happened? We’ll let one of the study authors explain. He said, “Our hypothesis is that Venus may
have had a stable climate for billions of years. It is possible that the near-global resurfacing
event is responsible for its transformation from an Earth-like climate to the hellish
hothouse we see today.” Like Earth, Venus was hot and then cooled. During the cooling phases there would have
been lots of carbon dioxide, but that would have come down and been trapped in the rocks. This would have left room for a lot of nitrogen
in the atmosphere, similar to what we have on Earth. The scientists wrote that during this long
period, some three billion years, Venus “had surface liquid water, plate tectonics, and
subsequently a stable temperate climate akin to that of Earth.” They believe this because they created simulations
of how the planet evolved. But then it all changed, and Venus experienced
this event that made it the horror show of a planet it is today. “Something happened on Venus where a huge
amount of gas was released into the atmosphere and couldn’t be re-absorbed by the rocks,”
wrote the scientists. They believe that volcanic activity might
have been to blame for the Venus we have today, with lots of magma being released. Magma is molten rock, the stuff we call lava
when it gets to the Earth’s surface. The researchers believe that this magma could
have released lots of carbon dioxide but when it cooled it couldn’t reabsorb the stuff
and so it stayed around, creating that terrible hot house. Imagine that, Venus could once have had an
atmosphere and environment like Earth’s. Does that mean life as we know could have
happened there, too? Could we have sent interplanetary text messages
to each other if it had stayed that way? Well, researchers said that in the past it
might have been possible. Those researchers concluded, “Our models
show that there is a real possibility that Venus could have been habitable and radically
different from the Venus we see today.” What do you think Venusian life could have
looked like? Could an intelligent species have once lived
there? Tell us in the comments. Now go watch “Most Extreme Planets In The

  1. That's how earth will look like in a million years. Imagine other life forms eventually finding our planet, wondering if it ever sustained life…
    All of history, everything we ever knew or achieved would be meaningless if we really let it ruin our planet, and would ultimately be the thing to cause our extinction.

  2. I wish we had the technology to fix certain planets to fit our needs. Imagine making Mercury Venus and Mars habitable for humans? The 4 major powers could have there own planet and hopefully there would be enough room for the wars to stop

  3. My theory is that mercury had life until it got too hot, then life appeared on venus when it got hotter (every planet moves closer to the sun or gets hotter with time cant remember why). Venus then got too hot and life died again. Earth then got hotter and life could live on earth, however earth is getting hotter and hotter and soon life will die out and next is mars

  4. The reason Venus show hot is two reason.

    1) the distance to the sun. If you double the distance to the heat source, you square the amount of heat you get. The earth get 1000 watts per square meter. Venus gets 1m watts per square meter.

    2) The planet is covered by a 15km thick cloud of so2 ice. Sulfuric acid ice clouds are highly reflective of infrared, meaning that the infrared that co2 releases below the clouds are all reflected downwards.

    The volcano's on earth spew out sulfuric acid clouds but the earth is never completely covered. On earth the reflection of sunlight away more than compensates for the infrared that it reflects back, causing the earth to cool.

  5. So basically what we’re currently doing to earth…

    What if we came to Earth because we killed Venus and now we’re killing Earth and Elon Musk is trying to go to Mars…

  6. What if humans originally lived in Venus and after a cataclysmic event that destroyed Venus some of the Venusian humans fled to earth and became the first earth humans? ?

  7. i am skeptical whenever i hear yet another hypothesis of how x planet "used to be like earth". it seems every planet "used to be like earth" now. That sounds way too convenient and it would make a lot more sense if those planets where allways un-inhabitable. Unless people are trying to scare other people into thinking the earth is "next" or whatever.

  8. What if intelligent life lived on Venus until they polluted their planet so much that it became the Venus we know today. If this is true maybe one day Earth will be like Venus if we continue destroying it.

  9. What if climate change on Earth is the same as what happened to Venus just 750 million years later…

    What if Earth follows the same hellish path that Venus took…

  10. venus people smoked too much and exhaled too much sulfur and carbon die oxide, as it's evident from it's atmospheric composition. and they perished the industrialists' death.

    we just need to go there and dig the whole story up.

  11. Humans must exist somewhere else that's not earth because how would humans exist they must of come as a bacteria off a astroid

  12. Plot twist (thumbnail image): Venus became less deadly, because it went from blue fire to red fire. Red fire has less heat.

  13. I love infographics, but all of those smart can't figure out we were not lucky, it was not by chance where we located. It was only by God's prefect design.

  14. What if there was life on Venus and climate change happen and then they moved to earth and now we are trying to move to mars?Interesting?

  15. life is pretty flippin Buff. Like the tardigrade and the stuff that lives at the bottom of the Marianas Trench. What I'm saying there might be life on Mars, venus, or pretty much anywhere. Evolution would make it possible to be a multicellular organism, but most likely it will be a single cell organism, like a amoeba.

  16. It’s as likely that life started on Venus and was transferred to Earth as it is that life started on Mars and transferred to Earth. It has also been suggested that life could still exist in the upper atmosphere.

  17. What if humans used to live on Venus and we heated it up and then killed it and then a meteor carrying bacteria carried a bacteria that begins the path to human evolution here and were just going to turn Earth into Venus 2.0

  18. I didn’t know everyone else didn’t know this I am not even like an astronomer or anything I just know things like this

  19. Now do the same video for Mars. Mars ALSO has an atmosphere of 97% CO2 and it's avg global temperature is MINUS 60° C. It's NOT CO2 causing the retention of heat.

  20. You can only see Venus without a telescope at a certain time and certain place? It's the 2nd brightest object in the night sky, all it has to be is in your line of sight lol

  21. We actually came from Venus. Humans destroyed that planet by causing climate change and the survivors came here. With time we forgot where we came from. We are now in the process of the same destruction. We never learned from our mistakes.

  22. I think Venus was trying to tell us people on earth a message…. Global warming is real and soon Venus will have a identical twin and millions of years from now there will be a video called “How Earth became the twin of Venus”

  23. That close to the sun I'm pretty sure the UV radiation would have killed any kind of life that even tried to get started. Having the thinner atmosphere necessary to stay cold enough would have only let in even more UV. Think Sunburn, but all of you… and dead.

  24. This all seems possible, however this doesn't explain Venus's opposite rotation. There is a chance that a large object hit Venus in the past which changed it's rotation and created environment like it is today.
