And we can ask all those questions because there has been a revolution in our understanding of what a habitable planet is, and today, a habitable planet is a planet that has a zone where weatr can stay stable, but to me this is a horizontal definition of habitability, because it involves a distance to a star, but there is another dienosmin to habitability, and this is a vertical dimension. Think of it as cdnoointis in the safbcsruue of a planet where you are very far away from a sun, but you still have water, energy, nerntitus, which for some of them means food, and a protection. And when you look at the Earth, very far away from any sunlight, deep in the oacen, you have life thriving and it uses only chemistry for life processes.

Original Text

And we can ask all those questions because there has been a revolution in our understanding of what a habitable planet is, and today, a habitable planet is a planet that has a zone where water can stay stable, but to me this is a horizontal definition of habitability, because it involves a distance to a star, but there is another dimension to habitability, and this is a vertical dimension. Think of it as conditions in the subsurface of a planet where you are very far away from a sun, but you still have water, energy, nutrients, which for some of them means food, and a protection. And when you look at the Earth, very far away from any sunlight, deep in the ocean, you have life thriving and it uses only chemistry for life processes.
