I still think the Russians landing Venera-13 on Venus back in 1982 is one of the greatest scientific achievements of all time. The fact that it was able to survive for 2 hours in that environment and take pictures is absolutely incredible
I think only the Russians at that time could do what they did. A lot of cold war Soviet stuff might not have been pretty, but was made with durability for n mind
My father always speculated that something big passing through the solar system disturbed Venus so violently that it reversed rotational direction, which explains not only the retrograde direction but the slowness of it. He wondered also if that same disturbance, or one like it, was responsible for removing most of Mars's atmosphere, since our science suggests that Mars should have a much denser atmosphere than it does. This new discovery is consistent with my dad's theory -- a gravitational disturbance so great that it may have ignited tectonic instability in the planet which is still going on.
@@khalilweatherspoon2218 Unfortunately he died about 13 years ago, but he was a legit genius. Astronomy wasn't even his profession. He was a mechanical engineer.
I wonder if had Venus not suffered the primordial impact that messed up it's rotation, if it might now be just a slightly warmer version of Earth. It's proximity to the sun doesn't account for it's extreme temperature. Even Mars at twice the distance from the sun as Earth, would likely be habitable if it was large enough to maintain it's magnetic field and hence, it's atmosphere. Really a shame, because Venus would be the perfect place to colonise and give us a backup planet.
It would just give humans something else to fight over. Got plenty of that here on Earth. Best we just screw up one planet as opposed to another if Venus was habitable.
Yeah we would fight over parts of Venus but it would be worth to be able to colonize it providing that Venus didn't have a technological civilization already.
Venus is a tough planet to photgraph. Usually best to do it during the day when it's higer in the sky. The hardest part is finding the planet while the Sun is still up, but it can be done. :)
You can only see Venus around sunset or sunrise, and only when its to the left of the sun, or the right. You can never see it during the night or in the middle of the day.
The mystery of Venus atmosphere seems simple, really. That's the default setting. Venus --unlike Earth - has no Moon despite comparable mass. Earth had taken monstrous hit early on, that had ripped enough material to form the Moon and also gases, which either escaped directly into space, or Moon was too weak to retain. In any case it is most unfortunate, that Mars and Venus haven't swapped places.
Venus more easily to terraform then Mars. Venus moon can be created artificially and excessive carbon dioxide can be removed and used for making oxigen and methane.
We often see an extreme brightened object near moon and start thinking it is star. No fellas, its not star, its third brightest object in our solar system after sun and moon called Venus.
Venus and Titan have more in common with each other than either does to any other Solar System object. Both certainly appear to be in the embryonic phase of planetary evolution.
Thank you for this video! We get so little about Venus- I sometimes wonder if people were so disappointed that it wasn't the swampy watery world the SF writers of the 50's and early 60's thought it was, that they've kind of stuck it on the high shelf, whilst the more promising worlds of Mars and Europa, and even Titan, got the lions share of attention. The fact that its now known Venus' many volcanoes may still be active does answer one mystery that perplexed scientists for some time, and allowed fringe elements to cook up some strange ideas. Even taking into account that erosion ( chemical or otherwise) of both landscape and impact objects prior to impact would have an effect, the surface of Venus, or certainly, large sections of it, were remarkably devoid of impact craters, so much so that ideas like ' Crustal overturn' flourished. Now it is clear that the lack of impact craters may be due to the fact that eroded or not, they have simply been buried under flows of lava and other volcanic products, instead of being engulfed in some strange resurfacing event!
Man, I have to know where you get your fantastic background music from. It is that perfect non-intrusive awe-inspiring music like what is found in the Mass Effect game series. It's wonderful.
How do they know that Venus isn't still evolving? Present day Venus could be a mirror of earth's past. Earth could be what Venus will eventually look like.
kelvin sucks for human comprehension, i get it, but it’s a thing because when you are comparing astronomical object temperatures it gets… inconvenient to compare millions and billions instead of just thousands places
I'm pretty sure this channel is an AI (bot)-generated script read by a human narrator. It's a shame these low-quality inauthentic videos are taking over the platform.
No, it would not be, Venus is still in a habitable zone, Venus is not a hell planet just due to its proximity to the sun, it has more to do with its atmosphere ... That distance from the Sun is fine as long as the planet's ozone works and there are no greenhouse gasses in the atmosphere to trap the heat! Earth could also turn into Venus if we continue to pollute by pumping CO2 into the air! That's what climate warming is about!
I often wondered about this. Just how close could the other planets be - to earth - without negatively affecting each other's orbits, etc. If Venus was only half as far away from earth as it is today. If Mars was only half as far away from earth as it is today. Would they be (too close) and cause a catastrophe ?
@@iamtheiceman Mars wouldnt matter. Mars is dead no matter how close or far away it is. Mainly because the planet is too small, so the inner cool has already cooled too much for it to fuel the planet with energy and life. The innercore no longer generates an electromagnetic field, blocking the suns radiation. Even if it was where earth was.. the suns radiation would have 100% killed off any chance of life on mars. And the planets too small to sustain an atmosphere. Venus has WAY more a chance than Mars does. The only thing stopping venus is it's greenhouse effect. The theory is that Venus WAS in the habitual zone when our galaxy first started out because the sun was much dimmer. Venus is theorized to of had oceans and plantlife, but it's greenhouse effect (similar to global warming) has overtaken it.
Uranus rotates in the same direction as us, the thing with Uranus is that it's polar axis is almost horizontal, so to our eyes it is on its side when compared to the other planets
Is JW going to give us new photos on our own planets? I know its busy looking out as far as it can, but im sure it can make some awesome pictures of Venus.
Didn't contain any actual pictures of Venus just computer generated pictures and the badly edited yellow photoshopped pictures....😢 Was hoping for some honesty
There have been no spacecraft landings on Venus, recently, but you expected new visible light photos of the surface? Where did you think those might have come from?
He did say how Venus would look like... You know the maps we use on earth and on your GPS, they are CGI... If it's not honest enough for you, go look for pictures people snapped in the sky... My god you're brainless...
Wait a minute... You guys don't even know what you're looking for... The real image of Venus would be a white ball... The other types of image made by using other types of method to get information of the area of Venus he actually showed us... But you thought images mean selfie like images you take with your iphone... If I give you a picture snapped in the 50s and you use Lightroom to clear it up, does that make it CGI??? You guys think, taking a picture means going over there and taking an iphone to it and taking the actual picture of Venus in iphone clarity... The information given by the Magellan satellite gives us the film of Venus in different types of views and we translate it into something people like you expecting iphone clarity can see... You know, how we do with earth when we want to show it as a whole...
The temperature of Venus is related to the atmosphere and the proximity to the sun, but not for the reason that most people believe the high temperature is mostly due to the extraordinarily high surface pressure and less atmospheric content. This is a commonly misunderstood factor and can be observed on Earth with changes in temperature due to minor air pressure reduction at higher altitudes. Consider desert environments with warm temperatures and lots of sun exposure but with snow at mountain tops. Here we are talking maybe a few psi of pressure changes but 10s of degrees difference. Now consider to 1350 psi surface pressures of Venus relative to the 15 psi sea level pressures on Earth. It is pretty easy to calculate the energy increase due to proximity, combined with the higher CO2 atmospheric absorption isn't enough to get the temperatures we see until you increase the per volume CO2 content due to the atmospheric pressures. If anyone doesn't mention the massive increase in CO2 content due to the pressures they are intentionally misleading you to point to the CO2 at all. It is some basic college physics to calculate the energy density, spectral energy, and CO2 spectral absorption and see that the energy difference isn't sufficient to get you close to the temperatures on Venus until you account for the air density and that becomes the major contributor.
1)We don't destroy our planet. 2)Venus was hit by a very large body (the size of the planet Mars) not so long ago. It is the reason why it is still so hot and rotate in a different direction than all celestial bodies in the Solar System.
"Although conditions on Venus are harsh..." Surely that has to make the shortlist for understatement of the year? 🤣 Great video, really enjoyed that, and was totally unaware about the active volcanism on Venus.
Does Venus have it's own moon. Could be one factor as to why it acts so funky compared to the other inner rocky " Yo" planets. Plus who knows it may have been blasted by a huge sunward CME being so much closer to the angry sun. A blast so monumentally powerful but struck in such a way as to set spinning in the opposite direction, the CME not really hitting planet head on but just enough to set the winds spinning and spinning and more spinning faster and faster and faster still as it climbed forcing the actual planet no option but to follow the wind. Either that por superman used Venus to practice his time reversal trick to save louice. Then forgot to stop it. Duh superman. Anywho. Withthe winds and the planet suddenly out of whack it sets off mass geologic upheaval, fissues pumping co2 volcanic eruptions all over all or any water surface or otherwise and any vapor all mixed with volcanic gases producing sulfuric acid nitric acid plus a few more im sure al of which slowly whipped at lower level then building steam as higherlevel and faster winds keep hurling this poison faster and faster and with the sun constantly beating the atmosphere making it denser and denser and hotter and hotter so hot and dense tis almost like a barrier letting only small amounts of heat and junk to radiate away. I say there is little hope of change for venus unless another CME or superman remembers and get Venus spinning with the rest of us. Who knows this time may even slow down the clouds and cool the temps when volcanoes settle down. Planet is still f** ked but at least might be able to study planet side one day. My two cents on venus is now over Ta Da and good bye and a beer or Three.
Higher gravity of Venus compare to Mars and higher mass of carbon dioxide and sulphuric acid compared to water and hydrogen.. .has allowed Venus to keep its carbon dioxide atmosphere from being stripped by solar winds. And yes, the solar wind has stripped Venus atmosphere of water... hydrogen, oxygen and nitrogen.
So I wonder why wasn't the Hubble telescope not commissioned to study Venus since being launched into space, especially now that the JWST has been deployed?!
Can Space Matter assure the viewers that all of the images in this video are actually OF Venus? I swear I saw the the recent eruption of an Iceland volcano. Not that I mind you using other images not of Venus, but you must label them as such to show scientific integrity and my respect for Space Matters as a real scientific channel.
It’s definitely true that the study of old data and images reveals new discoveries. I found some old photos of myself taken 40 years ago, when I was 19, and discovered I was much hotter than I thought I was at the time 🤔
No, it would instantly evaporate, then likely react with other compounds in the upper atmosphere. You would, however, likely form a permanent layer of water vapor there that would continually cycle thru cloud formation, rain, evaporation, then back to clouds, but the rain would evaporate long before it touched the surface. But in the long term, it would likely heat the planet up further, as H_2O is a more potent greenhouse gas than CO_2. If you managed to cool Venus' atmosphere by a few 100 C, you would likely condense out a huge ocean of liquid carbon dioxide. Eventually, the entire surface could be covered by hundreds of meters of liquid CO_2.
No. Venus can't be cooled like dousing a fire. Water in gaseous form is a greenhouse gas (albeit a weaker one) and would contribute to the heating of the planet. Ultimately, chemical reactions would convert the water into sufuric aid further adding to the problem. Terraforming Venus will be much more challenging than lobbing a few comets at it.
You got to fetch that water from one of Jupiter's moon's first, maybe catch a comet or two? Then breed massive amounts of microbes to gobble up all the greenhouse gasses. Bake for a few aeons, and te voilà a life world
The wind would slow down eventually without a source of energy because of friction. The wind comes from the overwhelming heat, that's the source of energy.
Should have been more precise and said that the planet rotates clockwise when viewed from above the north pole. There is no up or down in space, and when viewed from the south pole it does rotate counterclockwise and all the other planets rotate clockwise. Except Uranus which rotates on its side.
I’ve seen several docs saying the fact Venus is much closer to the Sun isn’t important to it temperature. This doc is correct: obviously the previous docs are wrong. Btw: no possibility in my view, there’s life on Venus
If you find the Final Real Images of Venus in this video titled The Final Real Images of Venus, let me know. I only got through three minutes of the aimless wanderings of the narrator before I gave up. All I saw was 95% various artists' conceptions and computer generated images, 5% stock video, and 0% Final Real Images of Venus.
So co2 and nitrogen trap heat?. So why does co2 and nitrogen stop combustion? As well as being used in welding processes to cool the weld and fire extinguishers.
At about 2:56 you say that the planet takes 243 earth days to rotate. But at about 4:31 you say the night is 58 earth days. How is this possible? accounting for dusk and sunrise shouldn't it be at least 100 days of darkness? Or a straight day night period 121.5 earth days?
These videos are good. But would be more enjoyable if you spoke scientific measurement. NASA and scientists use metric (kilometers, celcius, km/h etc) . Not old measurements of (miles, fahrenheit, mph, etc)
But why should the existence of active volcanoes, flowing rivers of molten rock, elevated hills or changing features on any planet in the solar system or elsewhere surprise anybody? Existence of a magnetic field or seismic activity etc would also be a natural result of their mere existence.
Terraforming Venus would be easier to achieve if we could move it to an orbit closer to ours (say 90 million miles from the sun) and give us the technology needed to migrate our excess population to a new world with a climate similar to ours. 😇
How could microbial life adapt to temperatures so high that liquid water cannot exist and where most chemical processes associated with biology cannot occur?
Hopefully future generations will be able to adjust Venus' and Earth's obit to cool Venus and make it habitable....and not end up with one or the other flung out into deep space!
... "no Venus missions till 2030 because funding was cut"... He forgot to mention that funding was cut due to funding wars around the globe. There is no money in Venus exploration, but there is money in wars!
@@nerdgenius915 I mean... it's a large planet, it should be warm inside. Like on Earth most volcanos are due to subduction zones, does Venus have only hotspot volcanos or does it have more interesting processes at work? (Not suggesting subduction)
I think Venus was like earth 🌏 before but something happened like the end of the world as a scientist predict the end of the world would be that the Earth spin the opposite direction
How is Venus 1/8 closer to the sun when the distances are , Mercury is about 33 million miles from the sun, Venus is 67 million miles away and Erath is 98 million. That would be 1/3 closer wouldn't it? art
Interesting video, but the mispronunciation of so many words suggests that the narrator is an AI program using a contrived accent rather than a human. I recommend a new soundtrack.
@@IamSkyeOrion well Jesus, as I was born in eastern North Carolina that is my native dialect. However, I learned the correct pronunciation of scientific words and names.
