Venus has always been hell – there are new climate models claiming that it has never cooled enough to be habitable

It is ironic that, at the same time that we discover traces of great lakes on Mars, our other neighbor Venus brings us diametrically opposite data. We know that today its surface is similar to the definition that we could have of a hell, but now there are new signs that her past was no different at all.

The orbital position of Venus raised some suspicions. Perhaps, billions of years ago and with a younger and colder Sun, Venus could have been a habitable planet. After all, it is very close to Earth, a planet that meets the conditions to host life.

Condense water vapor, the limit point that distinguishes the Earth from Venus

But from ScienceAlert they reflect the conclusions of new studies that include climate models of the planet in its early years, with its surface completely melted. So that any trace of water vapor that might have existed would turn into liquid it would have taken Venus to have cooled for several thousand years, with clouds capable of blocking sunlight.

That would have been impossible, since the clouds that would have been needed to cause this cooling could only have formed in the half of the planet opposite the Sun. Furthermore, the same clouds they would have worsened the greenhouse effect that traps heat from the surface.

In other words: Venus has always been an extremely hot place where life is impossible. At least the life we ​​know. Furthermore, if the Sun had emitted more radiation, the Earth could have ended up like Venus with water that could only have existed in the form of steam.
