Парадокс дейтерия: был ли на Венере океан? | Документальный фильм

#Space #Science #Planets Nine hours. That's how long all the spacecraft that have ever reached Venus spent on its solid surface. Everything else you've read about this planet is the conclusion drawn from those nine hours. Venus is almost identical to Earth in size, mass, and the structure of its interior. It formed right next to us, from the same material, at the same time. And yet, it arrived at 92 atmospheres of carbon dioxide, solid clouds of sulfuric acid, and a surface temperature of 465 degrees Celsius—hotter than Mercury. Ten spacecraft landed there, and none survived longer than a little over two hours. The main question remains: did Venus ever have an ocean? Its atmosphere contains approximately 150 times more deuterium than Earth's, and this is the signature left by water escaping into space. Only a slow drip of volcanoes and comets, without any sea, would leave exactly the same signature. Three independent calculations yield three different answers: an ocean for almost the entire history of the planet, no ocean for a single day, no water at all. And the planet continues to betray itself. In a thirty-year radar archive, a vent was found that has changed over the course of eight months. The cloud layer orbits Venus in four days, while Venus itself rotates in 243 days, and each day there is a different length because the air and rock counteract each other's rotation. Phosphine hangs in the clouds, but it has nowhere to come from, and an instrument clogged with a drop of acid in 1978 has, over the past 47 years, produced two opposing conclusions about the same thing. You will see a planet that has erased its own biography, and people trying to decipher it from fragments. The answer will likely come in the 1930s, with a landing on an ancient tessera. What do you think: was Venus a second Earth or a furnace from the very beginning? #Space #Science #Planets #Venus #SolarSystem #Astronomy #Planetology #LifeInTheUniverse 💸 Donate for channel development (thanked you in the next video): https://www.donationalerts.com/r/slee... 📌 Our Telegram channel: https://t.me/+FWtFccUupzZkNWNi
