The surface of the Earth is the shore of the cosmic ocean. On this shore, we've learned most of what we know. Recently, we've waded a little way out, maybe ankle-deep, and the water seems inviting. Some part of our being knows this is where we came from. We long to return, and we can, because the cosmos is also within us. We're made of star stuff. We are a way for the cosmos to know itself.

The Cosmos is rich beyond measure — in elegant facts, in exquisite interrelationships, in the subtle machinery of awe.

The surface of the Earth is the shore of the cosmic ocean. From it we have learned most of what we know. Recently, we have waded a little out to sea, enough to dampen our toes or, at most, wet our ankles. The water seems inviting. The ocean calls. Some part of our being knows this is from where we came. We long to return.

Consideraba que había aprobado la prueba por pura casualidad, ya que por azar había respondido bien a numerosas preguntas de elección múltiple. Con escasos conocimientos, solo lo necesario para excluir todas las respuestas menos dos, tenía una posibilidad entre mil de obtener todas las respuestas correctas, se dijo. Para lograr veinte, las posibilidades eran de una entre un millón. Sin embargo, ese mismo test lo habían realizado quizás un millón de jóvenes en todo el país. Alguno había de tener suerte.

If we are merely matter intricately assembled, is this really demeaning? If there's nothing here but atoms, does that make us less or does that make matter more?

The Earth is the only world known so far to harbour life. There is nowhere else, at least in the near future, to which our species could migrate. Visit? Yes. Settle? Not yet. Like it or not, for the moment, the Earth is where we make our stand. It has been said that astronomy is a humbling and character-building experience. ... To me, it underscores our responsibility to deal more kindly with one another and to preserve, and cherish, the pale blue dot; the only home we've ever known.
