VENUS | The Real Surface is a Nightmare

追加: 2026-05-27

[00:00:01]Let's start with the atmosphere.

[00:00:03]Because before you even reach the surface, Venus will try to kill you in three completely different ways.

[00:00:10]The first is pressure.

[00:00:13]At the surface of Venus, atmospheric pressure is 92 times greater than on Earth.

[00:00:19]That's [snorts] equivalent to being 900 m underwater in our oceans.

[00:00:24]Your body wouldn't be crushed. It would be obliterated instantly. [music] The second is heat.

[00:00:32]The surface temperature averages 465° C.

[00:00:37]Not because Venus is close to the Sun.

[00:00:40]Mercury is closer and its surface is far cooler.

[00:00:44]Venus is so hot because of a runaway [music] greenhouse effect.

[00:00:48]Carbon dioxide and sulfuric acid clouds trap solar energy so efficiently that heat simply cannot escape.

[00:00:57]Ever. Think about that.

[00:01:00]A planet [music] that has been slowly cooking itself for billions of years.

[00:01:05]The third threat is the clouds themselves.

[00:01:09]From about 45 to 70 km altitude, Venus is wrapped in a continuous layer of sulfuric acid droplets.

[00:01:17]Not mildly acidic.

[00:01:20]Pure sulfuric acid.

[00:01:22]The kind that dissolves metal on contact.

[00:01:25]And the winds up there at cloud level can reach 360 km/h.

[00:01:32]The entire cloud layer circles the planet every four Earth days.

[00:01:37]Below the clouds at the surface, winds slow to a gentle breeze.

[00:01:43]But it doesn't matter. It's still 465°.
