Venus 101 | National Geographic


(ethereal music) – [Angeli Gabriel] Named
after the ancient Roman goddess of beauty, Venus is known for its
exceptional brightness in the night sky. But behind this facade is a
world of storms and infernos unlike anywhere else in the solar system. Venus, the second planet from the sun, is very similar to Earth from a distance. But up close, it’s a very different world. Venus is about the same size as Earth, just slightly smaller. It’s structure is also nearly identical, with an iron core, a hot mantle, and a rocky crust. The crust of Venus, however, is dotted with thousands of volcanoes, including Maxwell Montes, a volcano almost as tall as Mount Everest. Venus also has a thick layered atmosphere. It’s full of clouds that rain
(thunder cracking) sulfuric acid, and whip around the planet at speeds up to 224 miles per hour. Faster than some category five hurricanes. The atmosphere is so thick that it creates a surface pressure similar to what it would be about half a mile deep
in the Earth’s oceans. This pressure is heavy enough that a human standing on Venus’ surface, would be crushed. The atmosphere is made
of greenhouse gases, primarily carbon dioxide. Which create an extreme
case of global warming. They trap the sun’s heat, causing surface temperatures to rise over 880 degrees Fahrenheit. Making Venus the hottest
planet in the solar system. Venus is so inhospitable, neither humans nor space craft are able to survive the planet’s surface. But some scientists speculate that Venus wasn’t always so unwelcoming. From roughly 2.9 billion
to 715 million years go, global temperatures on Venus may have been just a few degrees cooler than Earth’s are today. And scientists theorize that the surface may have contained shallow oceans that could have held enough
water to support life. (bright instrumental music) Today, life may still
exist in Venus’ atmosphere. About 30 miles up in Venus’ clouds, where the temperature and surface pressure are similar to those on
the surface of Earth, scientists have observed
strange dark streaks that appear to be absorbing
ultraviolet radiation. A phenomenon that could be evidence of microbial life. Life may struggle to survive in the atmosphere of Venus, but it is this unforgiving environment that’s made Venus an icon of beauty. It reflects 70% of all the sunlight that reaches the planet, which is why Venus shines more brightly than any other planet or
star in the night sky. While more than 40 unmanned space craft have visited this infernal world, Venus, so illuminated in
the darkness of space, still has much to reveal.

  1. Venus is very similar to Earth from a distance, but up close is a very different world. If you'd like to learn more about the second planet from the Sun, read on here: https://on.natgeo.com/2yJFhrG

  2. if you put an expanding silver sheet ball (or balls) at Venus's L1 point so as to cover the planet in shadow, it will cool to a point were the atmosphere will turn into dry ice. Then you could land on it and bury the ice, reduce the silver balls to a size that lets just enough of the sun's energy to reach the planet's surface equal to that of earth's, and then Venus could be colonized by humans.

  3. Looks like we lived on venus. Then due to global warming we needed a new planet. So we nuked this "earth thing" and made the dinosaur meteorite story. Now we soon need mars. Here we come, red guy!

  4. About the same size as Mars but has the same problem women😍 do; Very hot, but acidic and creates lots of pressure!! Carfrul guys!

  5. Venus is not hot because of the effects of greenhouse gases. Venus is hot because of the effects of pressure on gases. This is proven conclusively 7 kl above the surface where carbon is still far more dense than Earth's carbon content But similar temperatures to Earth.

  6. The nine 9 planets are actually the 9 emperor's or 9 Gods. Egyptians knew it Mayans knew it other cultures knew it. Did you know it

  7. Far more interesting than that dead, freezing, dustbin we call Mars. I wish we’d spend more resources on Venus and some of the gas giant moons like Europa and Titan. The chance of finding life is seemingly much higher. I just don’t get the fascination with Mars. In my opinion, it’s probably the most boring planet after Mercury.

  8. Venus's surface temperature is so high because of the greenhouse effect. When I see venus, I am scared that earth will become venus because we are still destroying our earth by using fossil fuel. So we should reduce the amount of such things we consume.

  9. Maybe there was life long time ago and the planet is dead now due to changes of gravitational force as a consequence of changes in rotational speed. Hence it veiled with thick cloud and unsuitable for life. May be it's dead like our earth will be many billion years later.

  10. Wait…what!?!? No mention of Venus' *retrograde rotation*, one of it's prime attributes and what makes it different than any other planet in the solar system?

  11. isn't that interesting that venus, the hottest planet, is named after the hottest goddess? 🤔 They were onto something

  12. 0:06 That's Seoul, where I live in(I'm pretty sure, not hundred percent though ㅎㅅㅎ). Light trail on the mountain is the ancient leftover wall that was made to guard the city. By the way Venus really stands out on that photo yet I could not but notice my city.

  13. So it's somehow trapping all the heat of the sun causing "global warming" but it's also reflecting 70% of the sun's energy?

    ?????

  14. How did they map the geography with the crazy atmosphere and storms they described? Id be interested in how they solved that problem.

  15. Earth : Yo Venus, can I have your number? You pretty hot

    Venus : Stop Earth you making me blush

    *Venus' deadly atmosphere and temperature now explained*

  16. Does the C02 originate from the volcanoes? Did the volcanoes produce the C02 that ultimately warmed the atmosphere and also "trap" the planets heat in? Thx.

  17. How can anyone in their right mind believe they can see Venus at night. You plebeian cross eyed droolers break out your models of the solar system and LOOK. Use your brains for something besides holding your ears apart. Idiocracy at its finest.
