Por transmitir tu pasión por la ciencia y por el cuidado de nuestro planeta, único lugar donde hay vida y todavía está por demostrar que sea inteligente. Cambió la vida de muchas personas con sus aportaciones y con su divulgación. Sobre todo en la serie Cosmos. Hay una nueva serie Cosmos y otra igual de buena, Marte. No te las pierdas!
