Astrônomia Eofoco
Quando você olha para uma estrela ou uma galáxia distante, você não está vendo aquele objeto como ele é agora. Você está vendo como ele era no passado. Isso acontece porque a luz leva tempo para atravessar o espaço. Quanto mais distante está um objeto, mais antiga é a imagem que chega até nós. É como se o céu fosse um gigantesco museu do Universo, onde cada distância revela uma época diferente da história cósmica. 🌌 Olhar para o espaço é, literalmente, observar o passado através da luz.
