El universo

If you are curious as a cat and you like to keep track like a good bloodhound, this collection is for you. In each book, Dog and Cat will turn to a great expert to answer all his questions. Like an ancient sage, our friends Dog and Cat love nothing more than the starry sky overhead. It is a wonderful spectacle that arouses your inexhaustible curiosity: how many stars are there in our galaxy? How did the universe begin? What will the other planets of the solar system be like? To answer these and many other questions, Perro y Gato have decided to ask Nanda Rea, a brilliant astrophysicist who knows everything, absolutely everything about the cosmos.
