A circumstellar habitable zone is defined in physics as the area around a star where a planet, given sufficient mass and atmospheric pressure, can sustain the existence of water in liquid form on its surface. This area is metaphorically called “The Goldilocks Zone,” inspired by a children’s fairytale. In the story, a little girl named Goldilocks, when faced with sets of three, always chooses the option that is “just right,” ignoring those that are too extreme — such as too hot or too cold.
In “The Goldilocks Zone,” water can flow, allowing life to exist in its—so far known—form. Water is essential for the development of life, and it is also the element that defines our most familiar place, where intimate stories are woven and memories unfold: our homeland.
